Slice the tops off the bell peppers and remove the seeds and membranes. Lightly brush the outside of the peppers with olive oil and place them upright in a baking dish.
In a medium saucepan, bring the vegetable broth to a boil. Add the quinoa, reduce the heat to low, cover, and simmer for 15 minutes or until the liquid is absorbed. Fluff with a fork and set aside.
In a skillet over medium heat, add a splash of olive oil. Sauté the chopped red onion and minced garlic for about 3-4 minutes or until softened.
Add the halved cherry tomatoes, chickpeas, olives, oregano, cumin, salt, and pepper to the skillet. Cook for another 3-4 minutes until heated through.
In a large bowl, combine the cooked quinoa with the sautéed vegetable mixture. Gently fold in the crumbled feta cheese.
Spoon the quinoa mixture evenly into each of the prepared bell peppers, packing it in lightly.
Cover the baking dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the peppers are tender and slightly charred.
Once baked, let cool for a few minutes before garnishing with fresh parsley.
Notes
Serve the stuffed peppers on a large platter, drizzled with a bit of olive oil and topped with extra parsley for a vibrant look.
