My sister-in-law makes these great 'pinwheel' wraps! These are made ahead of time (even overnight) and kept in the refrigerator until you're ready to serve them...
You just need some kind of sandwich wrap (any flavor), 2 or 3 kinds of lunch meat, 1-2 kinds of cheese, shredded lettuce, and diced tomatoes (if desired)... Then to keep the wraps together, she mixes sour cream, cream cheese, and any kind of spice that you like (She uses dill... I've used salt and pepper or Mrs. Dash... anything you like)
You mix up the cream cheese/sour cream mixture and spread it on the top 1/3 of the wrap. Place 1-2 slices of meat, cheese, a bit of lettuce and tomato... Then roll it up using the cream cheese mix as a 'glue.' You can wrap it in saran wrap and keep it in the refrigerator a few hours (or overnight). You don't have to overfill these... you get decide how thick or thin these will be.. They can be little appetizers, or the main meal like a hoagie...
When you're ready to serve, just slice it up in 1 inch segments and they look awesome, are light and delicious, etc..
Other ideas-
1. Soup station- There's an awesome baked potato soup mix that I've gotten at Shoprite... Black Bear? I add some sour cream and cream cheese... add a bag of steam and mash potatoes (red potatoes w/ the skin)........then have cheddar, bacon bits, and chives to add as condiments... You can make it on the stove and then have it in a crock pot...Guests can 'dress it up' as they like.
This would work with any kind of soup if that's too heavy.... I've made Campbell's minestrone before and dressed it up w/ Barilla tomatoe/squash noodles........etc...... and some chunky tomatoes.
2. A 'fancy' punch- You can make a punch out of just about everything! My favorite was a peachy, mango/passion fruit punch I made using some sprite, peach flavored seltzer, passion fruit and mango pulp (Usually in the hispanic foods aisle), some chopped up peaches, and a little bit of sherbert (peach, orange, or whatever flavor you'd like).
3. Cupcakes are awesome because you don't have to worry about cutting a cake... they are portable......... There are some gorgeous cupcake liners at the craft stores. (Bring a coupon to get a good deal)
4. You can make a really great salad using broccoli slaw (near the cole slaw in Shoprite), add diced or shredded carrots, some craisins (I like the cherry flavored), cherry tomatoes............chopped up celery (totally optional), and then the dressing I like is a mixture of honey, mayo, white wine vinegar, and a touch of mustard. It's like a tangy honey mustard dressing. but- you could use whatever you have on hand and let people dress it themselves. I made mine in a salad spinner so I could spin it every hour or so to re-mix the dressing.
5. Have a few munchies ready to go as soon as you get back to the house to give yourself time... Chips and dip are always a hit...........you can also have a plate of cheese slices, pepperoni slices, and crackers ready to go. Take the cheese/pepperoni out of the refrigerator........open the crackers and you're ready to go.
You can also mention to some of your really understanding and helpful guests that you're looking for ideas. Someone may offer to bring something! You could make it a pot luck!
Good luck!
