chicken tortilla soup

My neighbor makes the best chicken tortilla soup I've ever tasted.  I finally got the recipe and it has quickly become one of my families favorite meals.  I make mine in the crock pot .

1 white onion chopped
1 can black beans drained
1 can kidney beans drained
1 can pinto beans drained (I left this out today... we ran out)
2 cans Rotelle chopped tomatoes and green chilies
1 can corn
3-4 cans chicken broth
1 pkg taco seasoning
1/2 pkg ranch seasoning
tortilla chips
cilantro
cheese
chicken... she uses a whole rotisserie and shreds it (much easier) I used about 5 or 6 chicken thighs that I had to cook prior so I could take the skin and bone off.  You can also use 4 frozen or thawed chicken breast.  *cooking chicken prior to adding in crock pot is not necessary, it really does all cook together

add all the ingredients into the crock pot and mix around

set to low for 6-9 hours or high for 4-5 hours depending on your crock pot

Crunch up the tortilla chips and sprinkle on top with cilantro

Enjoy
