Steps
1. Preheat the oven to 375°F (190°C).
2. Cut the eggplant in half lengthwise and scoop out the flesh, leaving about 1/4 inch of the skin. Reserve the flesh for the filling.
3. Brush the eggplant halves with olive oil and place them on a baking sheet.
4. In a pan, heat olive oil over medium heat, add chopped onion and minced garlic, and sauté until translucent.
5. Chop the reserved eggplant flesh and add it to the pan, cooking for an additional 3-4 minutes.
6. Stir in the cooked quinoa, feta cheese, oregano, salt, and pepper. Mix well.
7. Stuff the eggplant halves with the quinoa mixture and bake for 25-30 minutes, until the eggplants are tender.
8. Garnish with fresh parsley before serving.
