To begin, you’ll cook the ground beef and diced red onion together in a Dutch oven (or other soup pot) until the beef is browned and the onion is tender. Drain off any excess grease if necessary.
Add in the chili powder, cumin, oregano, salt, black pepper and cayenne. Stir it in.
Add in the cubed zucchini and diced carrots. Those will cook for just a minute or two.
Add the tomato sauce and beef broth.
Bring this all to a boil, reduce the heat to a simmer, cover and cook for about 10 minutes or until your vegetables are just tender.
