I save my peels in a bag in the freezer and when it’s full I make vegetable stock with it.

Don’t do potato peels but everything from broccoli stalks to mushroom stems work really good.

Sometimes if there aren’t enough onion parts I add an onion.

Then I freeze it in ice cube trays and then store them in an airtight container

I peel carrots to give the peels to my dog because it is her favorite.

I peel pumpkins/squash that aren't roasted, and potatoes if they will be fried (very different texture and they are unhealthy anyway), what other vegetables do people peel normally? I am coming up blank.

Only thing I think really should be peeled is thick stocks of asparagus, but thats more about them not coming out with a Woody texture when cooked.

I had a friend insist carrots must be peeled, and that the peels are inedible.
