That's HORRIBLE! I use tomato "products" all the time and have no idea what would be a good substitute. All the things you mentioned have to have tomato, don't they??

I use roasted red peppers. A lot of times it's a nightshade issue (tomatoes, potatoes, eggplant and peppers) but I can get by with bell peppers. For tomato sauce replacement for pasta and pizzas I mix some olive oil, grated garlic, italian herbs as a substitute. If you look online, there are some nomato sauces to make. They vary quite a bit so you may have to search for one that suits your palate.

You may just have to develop a taste for alternatives, like pesto sauces for pasta, white chile with chicken, etc. It would be really hard! Red peppers are great...I buy jarred roasted red peppers and they are so good and easy.

I never put tomato products in my vegetable soup, so that's easily remedied, just leave them out. I also make a white bean based chicken chili, but marinara? I've never tried to make that without tomatoes. I have made pasta with just some sauteed vegetables/olive oil/parmesan and I like it better than the tomato based stuff. Think macaroni and cheese with lots of vegetables in it!

I always thought marinara sauce is what we call tomato sauce so you can't really substitute that but there are so many other things you can do with pasta. The obvious ones are pestos, lemony sauces, chicken sauces..... endless options.

Chili - no idea!

Soup : no reason whatever to add tomatoes to veggie soup.

Try leek and potato, Celery, Asparagus, celery and apple is so good, seafood,..... good luck with a new adventure!

Pasta - use butter or evoo and grated cheese, pesto, lemon and butter, alfredo, etc. instead of tomato based sauces.

Ketchup - use mustard instead, especially on hot dogs. For french fries, use some mild hot sauce.

Barbecue - good barbecue don't need no sauce, but if you must - there are some great mustard and vinegar based sauces available.

Chili - search the web for "white chili" and/or substitute hot sauce without tomatoes.

Soup - unless it's tomato soup why would you put tomatoes in there?

Marinara - you're not going to make chicken parm without it, so you're better off finding something else to do with chicken breasts or just don't put sauce on them or substitute mild hot sauce.

I had an uncle who was diagnosed with a several allergy to nightshade vegetables. He was able to eliminate them from his diet and lived to be 88 years old. I don't know if he lived that long because he didn't eat tomatoes, but if you have the same problem, it's a serious situation that you can't ignore.

I agree with what others have said - for vegetable soup, use chicken or beef stock as a base - no need for tomatoes at all. What is the marinara for? Just think of other sauces you would like - olive oil, garlic, herbs & cheese, or depending on what veggies you like, could use a spin off of a pureed soup - like carrot soup.
