Made this recipe on Saturday. It was good but quite spicy--you don't need the fresh chile pepper in there. We used Trader Joe's brand enchilada sauce. We also used regular flour tortillas instead of god awful pita bread and added some French-cut onions.
The recipe is from the Food Network Show Weighing In, which is really quite good--meaning it probably won't last very long. It's from an episode about 3 fat guys, at least two of which played college football, I believe. So, the recipe appears to have been designed for someone who has no understanding of cooking beyond throwing a bunch of stuff into a pot and waiting around for a few hours. In this case, that's good enough. I actually seared the outside of the pork tenderloins (came in the usual package of two) instead of throwing them in raw. I didn't just do this for the added flavor but to play around with an indoor counter-top grill that's been sitting around since law school.
