Parts of plants not typically eaten

Does anyone get a good meal from parts of a plant not typically eaten? Examples could be sweet potato leaves or maypop leaves

I include sweet potato leaves in salad, I cook radish greens along with other greens, I use old radishes as a cooked vegetable, and eat radish seed pods in salad.

Cool! I eat carrot tops. Have not tasted radish greens but its on my list now

"Not usually eaten" depends upon your region and culture. So I'll list items (that come to mind at this moment) that I now eat living in Hawaii but didn't eat when I lived in NJ.

Sweet potato leaves and growing tips.
Radish and daikon leaves and stems.
Radish pods.
Onion leaves.
Beet leaves and leaf stems.
Chard stems.
Carrot leaves.
Pea tendrils and flowers.
Bean flowers.
Squash flowers.
Pipinola (aka chayote) growing tips and root.
Banana flower core.
Parsley stems.
Broccoli stem.
Watermelon rind.
Lemon and lime rind.

Plus I simmer parts for making stock but don't actually eat them (they get fished out afterward and fed to the livestock).....
Onion skins and discarded tops & root
Pea pods
Over mature bean pods
Stemmy parts of various herbs
Leaves of allspice and clove
Discarded tough parts of broccoli, cauliflower, cabbage, etc
Peelings from kohlrabi, parsnips, turnips, sweet potatoes, etc

Plus I've used fruit discards for making flavorings....
Banana peels
Pineapple rind and core
Lemon and lime rinds

I recommend Linda Ly's book (https://permies.com/t/47335/cooking/Linda-Ly-author-CSA-Cookbook).

this is a weird question, whaddaya mean "not usually eaten"?
not eaten by whom?
the burger binging concrete dweller?

I did not know, that you USUALLY DO NOT eat a lot of the things I always ate
why would I not eat the core of a pinapple?
or onion leaves? or leaves of caigua, chayote, beets, kohlrabi, carrots, radish, pumkin, nasturtium ...
or lot's of flowers? 1st bouquet of roses I got, I ate
why not eat Broccoli stems, it's still broccoli, right?
chards are grown for their stems
lemon + orange rind is sold candied, why not eat without the sugar?

pumkin, watermelon, ... seeds? dry, grind, use as flour
