Spicy Chicken Chili

This chicken chili is much better than chili made with hamburger, and it's really quick.  I have been making it for years.
You have to have cooked the beans ahead.   I cook extra beans when I soak and cook them so I always have some in the freezer.  

Ingredients
1 Tbsp. oil
2 garlic cloves
1 lb chicken thighs, cut into strips (boneless, skinless)
4 tsp, chili powder
1 T. cumin powder
2 tsp. dried oregano
1 tsp. salt
2 jalapeno peppers, chopped and seeded
1-1/2 cups chopped tomatoes (fresh)
1-2 cups chicken stock
2 cups any white beans, cooked
2 cups black beans, cooked
1/2 tsp black pepper
Fresh cilantro

Instructions
Saute onion and garlic for 3 minutes
Saute chicken 3 minutes
Stir in spices and tomatoes and stock.
Simmer 15 minutes
Add beans and simmer another 15 minutes.
Add chopped cilantro and serve.
