Heat 1 tablespoon olive oil in a large pot over medium heat.
Add ½ diced onion, 2 peeled and chopped carrots, and 1 sliced and quartered zucchini. Cook for 4-5 minutes, until the vegetables begin to soften.
Stir in 1 package frozen beef meatballs, 1 can diced tomatoes with green chiles, 1 can tomato sauce, 6 cups beef broth, 1 drained and rinsed can black beans, 1 cup frozen corn, ½ teaspoon salt, ½ teaspoon pepper, 2 teaspoons chili powder, and 1 teaspoon cumin.
Bring the pot to a boil then reduce the heat to medium and simmer uncovered for 15-20 minutes until the meatballs are cooked through and the veggies are the tenderness that you prefer.
Add in the zucchini and then simmer for an additional 5 minutes.
