Crock Pot Chicken Tortilla Soup

I truly loved this especially served with my cornbread

1 can black beans, drained (I also added in 2 cans kidney beans)
1 can corn, drained
1 can diced tomatoes (14.5 oz size - southwest style, if possible I used petite diced tomatoes w/ sweet onion)
1 packet enchilada sauce mix (I used 1/2 packet of taco seasoning and 1/2 packet of ranch seasoning)
1 1/2 C water
1 can (8 oz)tomato sauce
1 can ( 10 3/4 oz) cream of chicken soup
2 C milk
3-4 boneless chicken breasts (I only used 2 chicken breasts)
(I also added in onion and other seasonings like garlic)

In crock pot, mix the enchilada packet together with the water and tomato sauce. Add cream of chicken soup and milk and whisk together until smooth. Add chicken. Pour drained black beans, drained corn and diced tomatoes on top of that.Cook on low 6-8 hours.Before serving, take out chicken and shred or dice, then put back and stir it all together. Serve with sour cream, shredded cheddar cheese, lime, avocado, or tortilla chips. (We just did cheese and sour cream, we forgot about chips)
