The only one of those I truly hate are tomatoes . . . well, raw tomatoes anyway . . . otherwise, I like ketchup, and I really like tomato bisque soup, but that's about it. I like mushrooms very much, but only if they're fresh from the produce section, and not that canned junk that most people use in cooking. Onions? It's hard to find a good one, but I've found the smaller and flatter they are, they're not as overpowering.
