Chicken Taco Soup

I got this recipe from Life As A Lofthouse. I made it a few weeks ago and it was so good. I forgot to take a picture.

Chicken Taco Soup
1/2 cup chopped
Onion (I left this out)
1 Green Bell Pepper, diced (I actually left this out too only because I didn't have one)
1 (16 oz) jar of Salsa
32 oz Chicken Stock
1 (1.25 oz) package of Taco Seasoning
1 (12 oz) bag of frozen Corn
1 (6 oz) can Tomato Paste
2 lbs boneless skinless Chicken Breasts
4 oz Cream Cheese
1/2 cup Sour Cream
Avocado (Optional)

In a large crockpot, combine all of the ingredients EXCEPT the cream cheese and sour cream. Cook on Low heat for 6-8 hours. A half hour before serving, remove chicken breasts and shred. Return shredded chicken to crockpot and also add in the cream cheese and sour cream. Stir and let them both melt into the soup. Serve in individual bowls with shredded cheese, more sour cream, avocado and tortilla strips or chips!
