After reading this thread, I realized that alot of my favorite foods would probably classify as "odd". In college, I used to eat saltines with a dollop of barbeque sauce and dill pickle/miracle whip (never mayo!) sandwiches made on swirly rye bread.
Nowadays, I love a good spaghetti sandwich - take leftover spaghetti with just a modest coating of sauce that's been heated up in the microwave (so it gets really hot) and put it between two slices of squishy white bread. If I'm feeling really crazy, I'll slap on a slice of American Cheese or I'll put it in the sandwich maker so the outside gets crispy and toasty.
For a light snack, nothing beats romaine lettuce dunked in plain yogurt. Again, if I'm feeling crazy, I'll dunk corn chips in the yogurt.
I must've gotten this gene from my mom who loves a good peanut butter and pickle sandwich.
