Sweet Potato Leaves

My friend and her mother-in-law gave me a big bunch of sweet potato leaves to try (They grow them and only eat the leaves, whereas I only eat the root. hah!).
But I'm not sure what to cook them in.
Any ideas?

I was thinking just sauteing them with maybe some vegan oyster sauce. But I'd also like some other ideas that aren't the hum drum stuff I always make.
