Crockpot Nachos

We ended up eating this more like an open-face taco but it was really good! There's one thing in here that I'd never think to put in a nacho/taco recipe but I think it added some very good flavor!

1 lb. ground beef
1/4 cup green pepper, diced
1/4 cup onion, diced
1 pint taco sauce (I actually didn't use this)
10 3/4 oz. can cream of chicken or mushroom soup (this is the "secret ingredient" yummy!)
1 envelope dry taco seasoning
salt to taste
2 cups Velveeta or Cheddar Cheese

Brown beef with green pepper and onion. Add all ingredients to Crockpot and cook for 1 hour on high, stirring occasionally until cheese is melted. Serve with tortilla chips, lettuce, salsa, sour cream, ranch, guacamole, etc.
