I've just discovered pawpaw as a veggie! I've made an Asian style pawpaw salad before, which is really nice, however cooking it as a vegetable is delicious. I've only used really green pawpaws for both. As a cooked vegetable it's very similar to parsnip in taste. I've tried it roasted as well as fried. It's really nice fried in butter with garlic and onion. If you have a tree, give it a try, you will be pleasantly surprised.
