I was just at walmart and saw a package of two lamb breasts for about $6. Unknown cuts of a delicious animal at a suspiciously low price? Needless to say, I bought it.

Now, what is this thing and what do I do with it?

It has what looks like rib bones attached and the two pieces are somewhat large, so I was thinking of using the slow cooker or roasting it, but any suggestions would be great. I think I might be eating a lot of these if it turns out well.
