They're the worst when diced, especially in something like stir fry. Your chewing your rice/veggie similar consistency mix then all the sudden you get either a crunchy flake (for uncooked onions) or a tiny piece of wet paper (for cooked).

I realize this rant is childish, but my sensory issues make this a big deal for me and I need to put my foot down.. even if it causes my heel to light up.
