Thread: Vegetable peels

I've read that the trimmed peels and ends of vegetables like onion, carrots and celery can be tossed in a bag in the freezer and kept until you want to make chicken, vegetable or beef broth. Could this include the brown papery peels from onions? I would probably have to add some actual chopped carrots, onions and celery Everything would be strained out when the broth is finished.
