What Is This Red and Green Leafy Vegetable, and What Can I Do With It?

Good Questions

Q: This leafy green was labeled "Red Leaves" at my grocery. There are no other identifying markings except the name of the farm (Felix Chac Chuo Farms), and Google just comes up with a Faulkner story and pictures of Japanese maple trees. What is this weird green and what can I do with it?
