I use leftover grilled boneless chicken breasts for this (2 or 3 ought to do for 3 or 4 people):
Other ingredients:
1 can white beans
1 can diced green chiles, mild
1 can white hominy
1/2 small yellow onion, chopped
1 teaspoon diced garlic
2 teaspoons ground cumin
1 teaspoon ground chili powder
1 chicken bouillon cube
A few fresh cilantro leaves chopped up, optional
In a soup pot, saute the onion and garlic in a couple of tablespoons of oil (I use olive oil). When tender put in the canned items and add enough water to make the consistency that you want (2 or 3 cans). Add the bouillon cube and bring to a simmer. Meanwhile, cut up the chicken and add to the pot. Add water to your preference. Don't over-stir or keep on the stove too long or the beans will get mushy. Serve with chips -- dig in!
