1 can cream of chicken soup (okay, so this makes it not vegetarian, but it's close)
2 C. chicken broth
1 C. water
1 40z. can diced green chiles
2 T fresh cilantro
2 T taco seasoning
2 C. corn
2 C. chopped chicken or 1 can white beans
1 C. sour cream
In large pan combine all ingredients except sour cream (unless you are using beans, add those after you have simmered). Bring to boil. Reduce heat and simmer 15 minutes. Stir in 1 cup hot mixture with the sour cream; return to sauce pan and heat through.
(I also added a cup or so of cooked brown rice to bulk it up a bit when I made it with beans)
Serve with tortilla chips and shredded cheese.
