I highly recommend checking out kidswithfoodallergies.com You have to become a member ($25/year), but they also have scholarships if you can't afford the fee. They have a recipes section and forums including a few on cooking and planning meals. I've simply started making almost everything from scratch. That way I know that there aren't hidden allergens. (My daughter has milk and egg allergies) It does take a little while to adjust, but I think that now my family eats better than we did before we found about her allergies, just because I am more aware of everything that I'm putting on the table. You also need to watch out for cross-contamination if you are cooking safe and unsafe foods at the same time. The kids with food allergies site also has a list of ingredients that can indicate milk. I have a copy of it that I carry in my wallet.
I make the following things at home and get you some recipes if you are interested in any of them.
Spaghetti
Meatloaf
Beef Stew
Chicken nuggets
Tacos/Burritos
Pork Chops with rice and veggies
Chicken and noodles
Fake "Hamburger Helper"
Tamale Casserole
Pot Roast and veggies
Shepard's Pie
If I pull out my menu book I can get you more. I hope this helps. I've been down this road and I know how difficult it is, so I'm happy to help.
Oh, a couple of products that I've found extremely useful are Earth Balance Vegan Buttery Spread (replaces and cooks like butter) and Play Food. Play Food makes vegan cheese substitutes that taste almost just like cheese. They have cheddar, cream cheese, nacho cheese and sour cream. I just found these at the new Hy-Vee in Topeka, but I think the entire chain carries it. The Earth Balance you may need to get at a health food store and it can get expensive.
