Cha Cha's White Chicken Chili

Jordana gave me this recipe when I couldn't think of anything to make for dinner, and now it's one of our favourite dinners.

ingredients
1 T vegetable or olive oil
1 onion, chopped
3 cloves garlic, crushed
1 4oz. can diced jalapeno peppers (optional, makes it super spicy)
1 4oz. can shopped green chili peppers
2 t ground cumin
1 t dried oregano
1 t ground cayenne pepper
2 14.5oz. cans or 3-4 cups chicken broth
3 C chopped cooked chicken breast
3 cans white cannellini beans
1 C shredded Monterey Jack cheese (optional)

directions
Heat the oil in a large saucepan over medium-low heat. Slowly cook and stir the onion until tender. Mix in the garlic, jalapenos, green chili peppers, cumin, oregano and cayenne. Continue to cook and stir the mixture for about 3 minutes. Mix in the chicken broth, chicken and beans. Simmer for 15 minutes, stirring occasionally. Remove the mixture from heat. Slowly stir in cheese until melted. Serve warm.

notes
I usually leave out the jalapeno peppers and halve the cayenne pepper or it's almost too spicy. I also leave out  the cheese and it's still delicious. I also use one small rotisserie chicken from the grocery store instead of the chicken breast, and it's the perfect amount for dinner and leftovers.
