All of those recipies sound great. Since one of the requirements listed is that they shouldn't trigger common allergies, and as someone who lives with food allergies, I probably ought to point out that prepared foods like ketchup and canned soups, and also dairy products would all fail that requirement.

I know it's really difficult for people to know what to avoid if they don't have to deal with the specific allergies in question. It's very tricky even for those of use who live with them. But I thought I probably should point that out so people would know what they're dealing with if they want to try to avoid triggering people's allergies.

Substituting dried herbs and olive oil for the seasoning mix with the potatoes would probably be allergy proof. Also substituting tomato paste sweetened with honey and flavored with herbs and spices would probably be an allergy free substitute for ketchup for the meatballs. The cream of mushroom and/or celery soup contain dairy, so maybe a vinaigrette made from lemon juice, olive oil, and herbs would be a good allergy proof substitute for the canned soups on the noodles.
