So I can't eat...
Ham (I sure can't eat it by itself, but I recently had a calzone I didn't realize had ham in it until several bites it. It was so loaded up on pepperoni and sauce that they were all I could taste)
Milk (by itself... I love it in cereal, but I can't just drink a glass of it, blech)
Most melons (watermelon, cantaloupe, honeydew, etc)
Broccoli (this makes me feel like a child, but it's really putrid shit... I actually don't love a lot of cooked veggies, but broccoli is the most abhorrent)
Anything really spicy. I am a complete puss at heat.
Those are the things that jump right to my mind, at least. I'll definitely come back and add more as I think about this.
