My mother was and is an excellent cook but, when I was a young child, money was very tight and we would often have things like hamburger gravy on toast (ground beef in a white sauce..blech), chicken à la king (chunks of chicken and vegetables in a white sauce over rice or noodles), liver (which was cheap then) with bacon and onions, or her home-made spaghetti sauce that had big pieces of tomatos, green peppers, mushrooms and other stuff, usually served with shell pasta. The only thing I couldn't force myself to eat was the spaghetti sauce.
As a kid, I was always on the lookout for slugs and insects in my food (I found that sort of thing just often enough that I could never relax), and that sauce, with all of those things floating in it completely grossed me out. I remember many a night when I'd be sitting at the dinner table trying, for what seemed like hours, to choke down just enough of it to be excused.
