Ingredients

• 1 tablespoon olive oil
• 3 stalks celery, chopped
• 1 onion, chopped
• 3 cloves garlic, chopped
• 1 pound ground beef
• 1/2 pound spicy chorizo, casings removed and discarded
• 2 (28 ounce) cans tomato sauce
• 1 (14.5 ounce) can stewed tomatoes
• 1 (6 ounce) can tomato paste
• 1 (10 ounce) can diced tomatoes with green chile peppers (such as RO*TEL®)
• 1 (1.25 ounce) package chili seasoning mix, or to taste

Instructions

1. Heat olive oil in a large pot over medium-high heat. Saute celery, onion, and garlic in hot oil until tender, 5 to 7 minutes.
2. Stir ground beef and chorizo with the vegetable mixture, breaking meat into increasingly smaller chunks as you cook and stir until the meat is completely browned, 7 to 10 minutes.
3. Stir tomato sauce, stewed tomatoes, tomato paste, and diced tomatoes with green chile peppers into the beef mixture, respectively; season with chili seasoning mix. Bring the mixture to a boil, reduce heat to low, and cook chili at a simmer until thickened, about 1 hour and 45 minutes.
