Step 1

Heat a large Dutch oven over medium heat. Add the beef and onion and cook, stirring to break the beef into small pieces, until it is no longer pink and the onion is softened, 6 to 8 minutes.

Step 2

Stir in the garlic and jalapeño, if using, and cook, stirring, for two minutes.

Step 3

Stir in the tomatoes, taco seasoning, green chiles, chicken broth, corn, pinto beans, and black beans. Bring to a boil over medium-high heat. Reduce the heat to medium-low, partially cover and cook, stirring occasionally, until the flavors meld, about 20 minutes. Season with salt to taste.

Step 4

Serve, topped with sour cream, chopped cilantro leaves, cheddar cheese, and avocado, if you like.
