Heat the olive oil in a large saucepan or Dutch oven over medium heat. Add the onions and garlic and cook, stirring occasionally until onions are translucent.
Add the rest of the ingredients except for the chicken. Stir and bring to a low boil, then reduce heat and simmer, uncovered, for about 20 minutes.
Stir in the chicken and allow chili to simmer until heated through.
Notes
Fresh cooked or canned chicken work equally well. If using canned, you may wish to reduce the salt from the recipe.Omit the hot sauce if you're not a fan.Use chili powder instead of cumin if you prefer a more traditional chili taste.Any white beans will work. Serve with a variety of toppings such as cheese, sour cream, diced tomatoes, avocado slices, fresh cilantro, etc. Serve with tortilla chips.
