Simple (yet delicious) crockpot recipes like this one are a life saver on busy days! This did not dissapoint, and I'm sure it would work just as well with chicken or pork. I used a can of plain diced tomatoes instead of the Mexican style tomatoes because I don't care for the sugar that is often in the Mexican and Italian varieties of canned tomatoes. Since I didn't use the Mexican tomatoes, I added a small chopped onion, some garlic, and some seasoning (chili powder, cumin, and Mexican organo). Also, since I wanted the kids to be able to eat it, I only went with two of the chipotle peppers and froze the rest. Since I was making this to go with some leftover chili pepper pasta, I did thicken the sauce with the cornstarch. I also stirred in some sour cream and fresh cilantro at the very end. So very good and super simple. Can't beat that!
