I just remembered some more.
My mom puts salt on apple slices which made me start doing it. It's pretty great.
The best way to eat a fresh tomato is to slice it up, put a dollop of cottage cheese on top of each slice then on top of the cottage cheese, a glob of mayonaise. Then a ton of black pepper. A southern classic. Delicious.
My dad mixes a huge squirt of ketchup in with baked beans. He also dips plain potato chips in ketchup. It's not THAT weird but I still wince when I see him do it.
