Pepper Leaves

Over the weekend, I was grocery shopping at a Chinese supermarket and came upon these vegetables which I have not seen before. They were called Pepper Leaves. Any food item that has the "Pepper" word in it intrigues me. So I bought it. Took it home. Then I realized I do not know how to cook these "Pepper Leaves". Naturally, I browsed on Goggle to see what I can do with Pepper Leaves. Well, we will see what I can with it. Thoughts of pickling it came up. I love to eat pickles.
