I'll only eat food with onions if I can't taste the onions. Usually that means stuff like chili and stew. If I can taste the onion it is no good because I HATE onions. Least favourite food probably

I do like funyuns though, because apparently my brain decided not to taste the onion in it even though its supposed to taste like onion. And sour cream and onion chips are my favourite kind of chip. But again, can't taste the onion in it so there you go
