As for me:
-Not big on Mayo or lots of weird condiments unless it’s the focus of the dish. BBQ? Amazing, ranch on some random dish I wanted, nah.
-Most raw veggies. I’m a farm kid, and my dad can pluck a tomato off a plant and bite right into it; I tried that once and nearly threw up.
-I can’t really do salads. They’ve just never appealed to me, and ones with things in them I do like, well, I’d rather just eat said things separately.
I can’t think of too much more off-hand that I find unbearable. Condiments are really my big one. Ketchup is almost always safe, same with bbq, and maybe a bit of mustard, but I’d often rather just want to taste the actual food I’m eating.
