Holy cow, this sounds like a tasty way to forage the leaves of sweet potatoes.
Chao Fan Su Ye. One of the signature dishes of Taiwan!
I don't usually cook Asian food, but I can imagine this dish with garlic and olive oil. After last year's success, I've expanded my sweet potato bed.
And another tasty sounding recipe, African Stew with Sweet Potato Leaves. I'm unsure what makes it African, since the sweet potato is indigenous to South America, and I associate neither peas nor potatoes with African cuisine. Still, the recipe as an idea is appealing.
