I sauteed some spinach, and threw some salt and pepper on 1lb of shrimp, and sauteed that, as well, and added both to the bean/onion/cumin mix. I also substituted whole wheat tortillas (for the flour), Weight Watchers shredded Mexican cheese (for the Monterey Jack and the cheddar), and used Reduced Fat sour cream to top it. I also couldn't find enchilada sauce, so I used Old El Paso taco sauce, instead. It was easy and really delicious.
