Pot Roast Tacos??

I was just flipped through some photos in the album set aside for this blog and I found these. For the life of me, I can't remember what they are. I do, however, remember there was something interesting about them. If I had to take a wild guess, I would say these are pot roast tacos. I believe I took some left over slow-cooked pot roast, added some cumin and chipotle, and called them Tex Mex! Whatever they are, they look darn good and I would be happy to try them again!!
