Eliminating tomatoes

While I seem to be ok with small amounts of tomatoes, I have decided that I probably need to eliminate tomatoes from my diet. This is really difficult because so many things are tomato based! Pasta sauce/lasagne/all recipes with tomato sauce, etc. I can't think what to substitute for tomato sauce and tomato paste. Now, I won't be able to eliminate pizza sauce - that would be way too hard!!!
Tonight we are having the leftover turkey in wraps with a chocolate souffle for dessert (assuming it works out:)
I'm also planning on making apple chocolate chip muffins.
