White bean chicken soup

I got this recipe from two reliable sources. Brett's mom and my sister Nat. The two recipes varied a tiny bit but I took what I had from each one and it turned out really yummy. Don't you just love a good soup on a cold (using the term loosely) night?

2 Tbs. olive oil
1 medium white onion, chopped
2 cloves garlic, minced
3 chicken breasts, cooked and chopped
1 package frozen white corn
2 cans Great Northern or white beans, undrained
1 can diced green chilies
1/2 tsp. cumin
1/2 tsp. oregano
3 cups chicken broth
2 Tbs. lime juice

*Saute onion and garlic in olive oil until tender. Add to the rest of the ingredients in a big pot on stove. Bring to a boil, then turn heat down and simmer for 20-30 mintues. Serve with sour cream, shredded cheese, tortilla chips.
