Saute one large chopped onion and 2 cloves of minced garlic in olive oil. Add 4 tablespoons of chili powder, 1 large (28 oz) can diced tomatoes, a dash of oregano, thyme, cayenne, 1 bay leaf, and 1/4 teaspoon of cinnamon. Nestle in three large chicken breasts, turn down the heat, cover and simmer for 30 minutes until chicken is cooked through. Remove chicken and shred using two forks.
Add back the chicken to the pot along with a cup of black beans, and a generous handful of frozen corn. Serve with toppings such as mashed avocado, shredded cheddar, sour cream, tortilla chips, or chopped cilantro.
