Southwest Nacho Casserole

This was one of the Books & Snacks 2008 dishes. It makes a decent amount of food, so it would be good for a crowd.

Southwest Nacho Casserole

2 lbs lean ground beef (I did half beef, half turkey)
1 cup water
2 envelopes taco seasoning
1 can (4.5 oz) chopped green chilies
2 cans (16 oz each) refried beans
2 cups shredded Cheddar cheese (I used a four cheese blend)
1 cup chopped tomato
1/2 cup chopped green onions
1 can (2.5 oz) silced ripe olives, drained
1 bag gold tortilla chips (extra thick)
chopped cilantro if desired
sour cream if desired

1- Heat oven to 350 degrees. Spray 13x9 glass baking dish with cooking spray. Cook ground beef in a 12" nonstick skillet until thoroughly cooked. Drain and return to skillet.
2- Stir in water and taco seasoning into the skillet with the meat. Bring to a boil then cook for 2-4 minutes until thickened. Stir in chilies.
3- Spread refried beans into the bottom of the baking dish. Top with ground beef mixture. Cover tightly with foil.
4- Bake 30-40 minutes or until bubbly around the edges.
5- Remove from oven and uncover. Sprinkle with cheese, tomato, onion and olives. Arrange tortilla chips around the outside edges of baking dish. Return to oven and bake uncovered about 10 minutes or until cheese is melted. If desired, sprinkle with cilantro and top with sour cream. Serve with remaining tortilla chips for scooping.
