Heat olive oil in a saucepan over medium high heat.
Add garlic, onion, and bell pepper, and cook, stirring frequently until onions are translucent (about 2-3 minutes).
Stir in zucchini, corn, black beans, and green chili peppers.
Add tomato sauce, turkey, rice, chili powder, cumin and 1-1/2 cups water; bring to a boil, then cover and reduce heat to simmer until rice is cooked through - about 25 minutes.
Garnish with cheese and sour cream and serve immediately.
