White Bean Chili

I got this from my friend Paige's family recipe blog. I about died, it's SO GOOD! So perfect for a cold spring day.

1/2 lg onion chopped

3 cans white beans, rinsed and drained
3 cans chicken broth
1 sm can diced green chili's
3 cups diced cooked chicken
2 tsp oregano
1 tsp cayenne
4 tsp cumin
1 tsp garlic
1 cup sour cream
2 cups grated monterey jack cheese

1 can diced tomatoes (BEST part in my opinion, it's not called for but I LOVED adding them)
In large pan, cook the chopped onion in a little olive oil. Cook until done.
Add remaining ingredients, simmer about 30 min.

When ready, stir in sour cream and cheese, or sprinkle cheese in each bowl, I also added some cilantro and chips. MMMMM
