Shredded cheddar cheese, sour cream, chopped onion, pickled jalapeños and
hot sauce, for serving
In an enameled cast-iron casserole, heat the oil. Add the sausage and cook over high heat, breaking it up, until browned, about 15 minutes. Add the onions, bell pepper and garlic; cook over moderately high heat, stirring, until the onion is translucent, 8 minutes. Add the tomato paste and cook for 3 minutes. Add the chili powder, paprika, cumin and oregano and cook for 1 minute. Add the tomatoes, beans, corn and water and cook over moderately low heat, stirring occasionally, until thickened, about 1 hour. Season with salt and pepper. Serve the chili with cheddar, sour cream, onion, jalapeños and hot sauce.
