Quick oats are still out there and going strong, but I always buy old fashioned if I'm going that route. I use steel cut oats a lot now, cooking them overnight so they're fully cooked and no crunchy bits.

Lima beans. I didn't like them as a kid and I don't like them now. Liver and kidney. Mom used to fix them when I was a kid but I think met so much resistance from us she finally stopped.
