In a large pot over medium heat, add lean ground beef and chopped onion. Cook for about 5-7 minutes until the meat is well-browned and the onions become translucent.

Stir in minced garlic and let it cook for an additional 2 minutes. Sprinkle in the chili powder, cumin, oregano, onion powder, garlic powder, salt, and pepper.

Carefully add 4 cups of beef or chicken broth, then add the drained corn, black beans, chili beans, crushed tomatoes, and green chiles. Stir to combine.

Cover the pot and bring to a gentle simmer over medium-low heat. Cook for 15 minutes, stirring occasionally.

Ladle the soup into bowls and let everyone customize with toppings such as sour cream, chopped cilantro, diced avocado, or shredded cheese.
