In a large pot, heat oil over medium heat. Drop meat into the pot and break apart using a wooden spoon. Cook until meat is cooked thoroughly.
Add in onions, garlic, carrots, celery, zucchini, and squash until slightly softened, 5 minutes. Stir in the remaining ingredients and bring to boil. Reduce heat to low and simmer at least 30 minutes.
Serve with desired toppings and cornbread.
