Avocado. Just the thought of eating this disgusting slimy, mushy crap makes me want to vomit.
My wife literally puts a half an avacado in with her lunch every day.
If we're talking food, it's onions. How can anyone eat these?
I'm all over onions. Put those fuckers in almost everything!
You and me. It's a joke in my family that I should be called "Cebby", short for "cebula", polish for "onion". I don't eat them like apples or anything, and I'm not a huge fan if they are raw, but if I'm cooking, I'll usually start with a saute of diced onions. I put onions in my ground beef, on my sandwiches, in tuna fish, in my guac. I'll saute onions in sherry or madiera and butter to eat with my steaks...
What I don't like: Diet soda in any form. Or sweet tea.
EDIT: Cauliflower. IT IS NOT A SUBSTITUTE FOR POTATOES OR PIZZA CRUST!
