I can't remember where I found this recipe but it works great for phase 1 of the South Beach diet. I have to double the recipe of I want leftovers because my family loves this dish! If I'm lucky, I get to freeze some too.
Preheat oven to 450. Spray a 7x11 or 9x9 casserole dish with cooking spray and spread refried beans on the bottom. Season with salt and pepper and bake for 15 minutes.
Meanwhile, saute meat, onions, & bell pepper (seasoned with salt & pepper) until onion begins to soften and meat begins to brown. Add garlic and mushrooms and cook until mushrooms have released their water and meat is thoroughly browned. Drain meat mixture and return to pan. Add all spices and cook for 2-3 minutes until spices are heated. Add green chilies and tomato paste. The mixture should be moist but not runny (add a little water if needed).
Pour meat mixture on top of the refried beans and top with the cheese. Bake for 10 minutes or until the cheese is melted.
NOTE: This is wonderful served on top of a bed of mixed lettuce. Garnish suggestions are: green onions, black olives, f/f or low fat sour cream, cilantro, salsa, etc.
