Jumpin' Jack Chili

This was SOOO good! I am a fan of white chili in general but this one was especially simple to make and still so flavorful. I wish I had more to eat for lunch today! (the recipe was in a little mailer I got from Wisconsin Cheese)

-1 c onion, diced
-1 t olive oil
-1 (4 oz) can green chiles, undrained
-2 cloves garlic, minced
-1 1/2 t cumin
-2 (15 oz) cans great Northern beans, rinsed and drained
-3 1/2 c chicken broth
-2 c cooked chicken, chopped, rotisserie chicken can be used (I used 1 can chicken)
-1 c Monterey Jack Cheese, grated and divided (I used all Monterey Jack)
-1 c Colby Cheese, grated and divided
-Toppings: crushed tortilla chips, sour cream, chopped green onions, tomatoes, avocado and cilantro, olives, bacon crackers
(some my suggestions and some theirs)

-Cook onion in hot oil in heavy stock pan over med-high heat, stirring until tender.
-Add green chiles, garlic and cumin; cook 2 min.
-Add beans and chicken broth, stirring well. Bring to boil; reduce heat, and simmer 20 minutes.
-Add chicken, 1/2 c. MJ cheese and 1/2 Colby cheese; simmer over low heat 10 min.
-Serve in bowls topped with remaining cheese and toppings of choice.
