Spicy Green Chile Mexican Casserole with Ground Beef, Black Beans, and Tomatoes

INGREDIENTS

1 can

(26 or 27 oz.) whole green chiles, drained (be careful not to buy whole jalapenos, which look similar)

1 can

black beans, rinsed well with cold water and drained

onion, chopped

2 tsp

+ 1 tsp. olive oil

1 lb

extra-lean ground beef (less than 10% fat)

1 tbsp

taco seasoning (I use my homemade taco seasoning, but a purchased seasoning will work.)

1 can

petite dice tomatoes with juice

eggs, beaten well

1 cup

Green Chile Enchilada Sauce (from a 15 oz. can, freeze the rest for another use.)

1 1/2 cups

Low-Fat Mexican Four Cheese Blend (I use the blend from Costco which has 6 grams of fat in 1/4 cup)

low-fat sour cream for serving (optional)
