Prepare the eggplant: Cut eggplants in half lengthwise. Scoop out some flesh to make a cavity. Brush with olive oil, sprinkle with salt, and roast at 200°C (400°F) for 20–25 minutes until tender.
Cook the filling: In a pan, heat 2 tbsp olive oil. Sauté onion and garlic until soft. Add tomatoes, chickpeas, spices, salt, and pepper. Stir in couscous (or rice/quinoa). Mix well and cook for 5 minutes.
Stuff the eggplants: Fill each roasted eggplant half with the mixture. Top with crumbled feta and fresh parsley.
Bake again: Return stuffed eggplants to the oven for 10–12 minutes until heated through and slightly golden on top.
Serve: Drizzle with olive oil, add a squeeze of lemon, and serve warm with salad or bread.
