On-the-go Meals Besides Sandwiches?

Trail mix, jerky, granola bars, carrot/celery sticks (you'll need a cooler and cold pack for that), apples, oranges, pears, etc.
Boredom with food is tough but I only put up with that for so long before I say they can go hungry for awhile and then they'll appreciate the snacks they get rather than complaining about wanting something different.
I provide healthy foods - it's their decision to either eat it or go hungry - it's totally their choice.

Make a big batch of plain meatballs. Saute chopped onions, and mix the onions in with some Panko bread crumbs and a little liquid (can be milk of any variety, or beef broth, or even water) until it's the consistency of slightly wet sand (not goopy or drippy). Then mix that in with ground pork and beef, or just ground beef, or ground turkey (change it up from time to time) but don't add other seasonings. Gently form into small meatlballs (bite-size), and bake on a sheet pan at about 350 until thoroughly cooked (about 15 or 20 minutes). Put them into zip-top bags when they're cool, and freeze some and refrigerate some.

Then you've got a blank canvas to work with. Meatballs with BBQ sauce and a half-ear of cooked corn on the cob. Meatballs in marinara or spaghetti sauce over pasta. Meatballs with teriyaki sauce or any Asian dipping sauce over rice. Meatballs on toothpicks with cherry tomatoes and a little slice of string cheese. Meatballs with cheese sauce over tortilla chips. Meatballs with pineapple cubes and crackers.

And you can grill up a bunch of chicken breasts or thighs. Same thing: chopped chicken over a hearty salad of greens and veggies. Chicken with BBQ sauce (just replace the word meatballs in the previous paragraph with chicken).

String cheese and deli meats (sliced ham) are good even without bread. Just roll the meat around the string cheese. Apples with peanut butter to dip them in. Hard-boiled eggs and cubed ham and some crackers.

Just get every kid his own small Tupperware or Rubbermaid container or thermos, label their name on it with a Sharpie, and buy a Costco sized supply of plastic forks, napkins and wet-wipes for hands and faces. Keep the napkins/forks etc in a bin in the car.

wraps...chicken, turkey or even a hamburger in a tortilla. We've made BLTs in tortillas for my oldest son's LAX team - they LOVE them!!

lettuce wraps - chicken with cashews - great protein - easy to handle.
One head of lettuce - use the large outside leafs
chop up chicken - add Hosin sauce or whatever sauce you want - diced carrots and celery
out in leaf, wrap up - enjoy.

Pasta salad with cut up chicken and veggies
A rice bowl or stir fry
What about burritos....there are so many different kinds you can make
Leftover Fried Chicken is always good
Subway type sandwich (but homemade)
Ok, now I am hungry!

We make whatever the plan for dinner is and pack it in a thermos if needed. The kids generally have enough time to eat whatever it is we have made before practice/game or after.

So we do things like chicken and rice, spaghetti, bbq chicken, tacos, stir fry, salads, hot dogs, burgers, leftovers, etc. Whatever really.

Last week my husband grilled some New York Strip, I made twice baked potatoes, and we steamed fresh asparagus with lemon pepper - I packed up my daughter's portion to go with her to dance class...so yes, even that type for us :).

Great question. Look forward to the answers. Only thing I can think of is some sort of cold pasta salad with a protein in it, shrimp or chicken. If it's packed in same size Tupperware, it could be pre-portioned and be ready to eat as each child has a chance/or is ready to eat. Also, some crockpot meals could be easily divided to take with you...i.e. stews, chili mac etc.

Snacks, not meals, correct?

Why not make them some things that are more complex carbohydrates like Oatmeal Peanut Butter Bars or something that has longer lasting ingredients that they will still enjoy.

We did a fresh fruit and the bars above quite often with the boys. Our girl detests oatmeal so she won't touch them. Otherwise I'd do a small meal like the sandwiches and then do another meal when you finally get home. A small meal can be anything.

If you're eating in the vehicle, pick them up and the food is in front of them, you can do any leftover if you pack it correctly. Heat it up, put it in styrofoam bowls or containers to keep it warm, then give them some plastic utensils and they can eat anything on the go, well maybe not soup...lol.

How about stir fry (chicken or beef) rice bowls? Each kiddo gets their own bowl to eat in the van or at
the ballpark with a spoon. We do homemade burgers (premade patties from Costco or wherever), only 20 mins
on the grill or on a skillet. Put on hearty kaiser hamburger buns, wrap in foil, eat in car. Steak sandwiches
(cook thin breakfast steaks in skillet, put on hoagie buns, w/onions or red pepper strips, wrap in foil).
Beef stew (make in crockpot) in individual thermoses for them to eat out of. Make a Stouffers lasagna night before, cut into squares, put in individual tupperware in fridge, day of game/practice take out of container heat on plate
in micro, put back in individual containers (will stay a little bit warm). Bake premade pizzas before you go,
bring to ballpark either in foil or buy a foil lined carrier like the kind they use to deliver pizzas. Make crockpot
meals in morning, when you get home it's ready, put into bowls w/a lid (they make glass ones now) & can eat in car
or at park. Buy premade chicken pot pie, cook night before so all you have to do is heat individual portion
sizes & put in tupperware to take with you. Taco salad (quick to make, can make night before just don't add
the "items that will wilt until day of" & can be eaten cold), bbq chicken breast in pitas w/veggies they
like, bbq chicken breasts (make a ton on Sunday, refrigerate, pull out portion/heat/put in tupperware w/some
warmed canned corn).

My kids liked stir fry chicken/vege noodle or fried/steamed rice dishes on the go. It's so easy to make extra when doing a stir fry or rice dish for dinner, and super easy to pack in thermoses or disposable coffee cups and I always had plastic forks in the car.
Another on the go meal they loved was scrambled egg, ham and cheese on a toasted english muffin or bagel, wrapped in foil to stay nice and hot. Sure that's technically a "breakfast" item but it makes for a healthy protein packed dinner as well.
