Heat olive oil in a large Dutch oven over medium heat. Once the pot is hot, add ground beef and chorizo (casing removed). Cook for 2-3 minutes, stirring occasionally, then add onion, bell pepper, and jalapeño.
Cook, stirring often, for about 3-4 minutes before adding the garlic and all spices. Cook, stirring constantly, for 1 minute.
Add the tomatoes, tomato sauce, beans, green chiles, and vinegar. Stir, cover with a lid, and place in the oven.
Cook for 4-6 hours, stirring throughout the day if you can.
Serve topped with cheddar cheese, green onions, and sour cream, if desired. Enjoy.
