In a large skillet over medium heat, heat the olive oil. Add the garlic, bell pepper, onion and corn. Cook for 5 minutes or until vegetables are tender.
Add the black beans, chili powder, cumin and salt and pepper. Cook for an additional 5 minutes.
Divide the quinoa among 4 bowls and top with the vegetable mixture.
