Cut the eggplants in half lengthwise and scoop out some of the flesh to create a boat-like shape, leaving about ½ inch of the border. Set the scooped-out flesh aside for later use.
Place the eggplant halves cut side up on a baking sheet. Drizzle with olive oil, and season with salt and pepper. Roast in the preheated oven for about 25-30 minutes, or until the flesh is tender and slightly golden.
While the eggplants are roasting, cook the quinoa. In a saucepan, combine the rinsed quinoa and vegetable broth. Bring to a boil, then reduce to a simmer, cover, and cook for about 15 minutes or until the liquid is absorbed. Fluff with a fork and set aside.
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the chopped onion and garlic, and sauté for about 3-4 minutes until the onion is soft.
Add the diced red bell pepper, and cook for another 3-4 minutes until slightly softened. Stir in the scooped-out eggplant flesh, cumin, smoked paprika, salt, and pepper. Sauté for an additional 5 minutes.
Add in the cooked quinoa, chickpeas, cherry tomatoes, Kalamata olives, and feta cheese (if using). Mix well and cook for another 2-3 minutes, allowing the flavors to meld.
Remove the eggplant halves from the oven. Stuff each half generously with the quinoa and vegetable mixture.
Return the stuffed eggplants to the oven and bake for an additional 10-15 minutes until heated through.
Once done, remove from the oven and let cool for a few minutes. Garnish with fresh parsley before serving.
Notes
Serve the stuffed eggplants on a large platter, drizzled with a touch of olive oil and sprinkled with additional parsley for a vibrant look.
