I didn't start to enjoy vegetables until I was out on my own. My Mother would boil everything in tons of water for a LONG time: canned beans, canned asparagus, corn on the cob, Brussels sprouts, cabbage, collards/kale. Canned asparagus does not boil well. Fresh corn on the cob shouldn't be boiled for an hour. Also, no seasoning, ever.
Spaghetti sauce was the cheapest ground beef, er gristle, with a can of tomato paste. Nothing else. Pasta would boil forever. White rice, only since "You don't want flavor in your rice".
Broccoli was always flowering, so was bitter as all-get-out. Sweet potatoes were baked into hardened masses. Hamburgers were solid hockey pucks (they crunched, IF you could bite them). Nothing but Wonder Bread, because any bread with any sort of body was "stale", even if it was still warm from the oven. Biscuits were kneaded into a wondrous toughness. Fish was fried into rubber. You could clank your knife against the steak. She even boiled the fish.
