Steps
1. Preheat the oven to 375°F (190°C). Cut the bell pepper in half lengthwise and remove the seeds and membranes.
2. In a bowl, combine the cooked quinoa, chickpeas, diced tomatoes, Kalamata olives, feta cheese, parsley, dried oregano, garlic powder, salt, and pepper.
3. Spoon the filling into the bell pepper halves, pressing it down gently.
4. Place the stuffed bell peppers on a baking sheet and bake for 20-25 minutes, or until the peppers are tender and the filling is heated through.
5. Serve hot and enjoy!
