Sushi - I have to eat with chop sticks.
Pizza - Has to have hot sauce.
Hamburger - Nothing but bread, meat, ketchup, pickles, and onions.
Taco - meat with lettuce, cheese, sour cream. (In that order)
Other than those specific's.... All my food can't touch each other or I won't want eat it.
I'm sure theirs alot more too, just don't feel like listing them all. I have a bad ocd case.
