Add 1 pie pumpkin, 28 ounces canned crushed tomatoes, 28 ounces canned black beans, ½ cup steel cut oats, 4 tablespoons chili powder, 3 tablespoons cumin, and 1 tablespoon dried oregano. Bring to a boil, reduce heat, and simmer until the oats are soft and the pumpkin is tender, about 25-30 minutes.
