Easy Mexican Casserole

This recipe could also be called Walking Taco Casserole.  

1 pound lean ground beef
1 can ranch style beans
1 can Ro-tel tomatoes
1 small onion, chopped
1 package taco seasoning
1 can cream of chicken soup
1/2 cup water
1 10-12 oz.bag tortilla chips, crushed (I didn't use the whole bag)
2 cups shredded cheddar cheese, divided
sour cream and salsa for serving

Preheat oven to 325 degrees.  In a large skillet, brown meat and drain off fat.  Stir in beans, tomatoes, onion, taco seasoning, soup and water.  Simmer over medium-low heat until everything is well combined and heated through.

Grease a 9x13 casserole dish.  Put down a layer of crushed tortilla chips, followed by a layer of the meat/bean mixture, then half of the cheddar cheese.  Repeat layers.  Cover with foil and bake for 20-30 minutes, or until bubbly.

Let sit for 5-10 minutes before serving.  Top with sour cream and salsa.
