Interesting thread!
I am amazed at some of the common food in question like peppers, mayo, onion in whatever capacity. For me,
1 No meat parts other than chicken, beef, pork, fish in the form to which we are accustom. With the exception of beef liver.
2 No runny eggs. They must be cooked all the way.
3 Anchovies
4 Peanut butter! Nothing in it, or taste like it! Just nasty all around!
5 there are a few things that i dont care for but will tolerate.
6 Bananas other than the real thing. No flavored stuff, candy, cake, or anything like that.
Thats all i can think of for now?
