Onions are amazing. They can work with practically anything. They are dirt cheap. They preserve very well. I guess the really "spicy" ones can taste "poisonous" if they're uncooked, since those can have a strong shocking flavor, but that's like... only if you're biting into a big chunk, which people don't usually do. Mince them up and simmer them in sauces or caramelize them and they're great. Fried onion rings? C'mon, they're great!
Says the knight who is made of onions!
But no I don't live on canned fish, I just enjoy it from time to time. ---
