Philadelphia, born early 80s. Mom hated cooking but did it anyway. Very bland basic food but all from scratch (by today's standards at least). Typical dinner was a plain broiled chicken breast (no skin, bones, or salt), baked potato with butter, and some kind of green veg: salad, steamed broccoli or asparagus, or frozen peas or green beans. Sometimes tomatoes if she was feeling into slicing something with a knife. Usually had fruit (strawberries, melon) for dessert. Snacks were carrot sticks or apples. She never cooked beef. She sometimes cooked turkey burger or fish to liven things up.
We usually had Chinese takeout once a week though, and once a month would go to a restaurant - Indian, Thai, Japanese, Chinese, or a very fancy high-end French or new American type place.
Lunch was peanut butter and jelly (even at Passover, we just switched to PB&J on matzoh) or bagel and cream cheese with lox.
When I got to college I was seriously excited at the number of choices in the dorm cafeteria - even though the quality wasn't great. Still, lasagna, meatballs, and spinach were exotic.
Like another PP, I taught myself to cook after college and never looked back. I favor highly spiced foods or foods with sauces. Probably a direct reaction to the flavorless chicken breasts of my youth. Still, considering, it was a pretty healthy - if boring - way to eat. At least, minus the takeout and restaurants.
