Stuffed Mustard Greens with Rice and Shrimp

Inspired by stuffed grape leaves which I like to make in late Spring when the leaves of our grapevines need some pruning. This time I used mustard greens which are growing wild in our raised boxes and from what I can tell are about to bolt too or send flower stalks to produce seeds, like the other leafy greens in the backyard garden. For the stuffing, I used rice and shrimp, wrapped in mustard greens and then cooked in seasoned water for about 20 minutes.
