Chicken and Bean Tortilla Soup

I made this the other night and I basically just threw it together with what I had in the pantry.

1/2 cup verde salsa

1 - 32 oz. box chicken broth

3 whole boneless chicken breasts

1 can black beans, undrained

2 cans cannellini beans, undrained

1 can diced tomatoes, undrained

1 packet taco seasoning

Let these ingredients cook for about 4 hours on high in your crockpot (or on low in mine since it is so hot!) During the last hour or so, add about 1 1/2 cups of frozen corn. Take out chicken breasts, shred and return to crockpot. Garnish with low-fat sour cream and shredded cheddar, if desired. Enjoy!
