01 - Preheat oven to 400°F. Line a baking sheet with parchment paper. Brush the cut sides of eggplant halves with 1 tablespoon olive oil, place cut side up on baking sheet, season with salt and pepper, and roast for 25 to 30 minutes until flesh is tender.

04 - Stir in diced tomatoes, ground cumin, smoked paprika, dried oregano, salt, and pepper. Cook for 3 additional minutes. Remove from heat.
05 - Scoop out some of the roasted eggplant flesh, leaving approximately 1/2 inch border, and chop finely. Add chopped eggplant to the skillet with vegetables.
06 - Add cooked couscous, fresh parsley, fresh mint, and lemon juice to the vegetable mixture. Mix thoroughly and adjust seasoning as needed.
07 - Spoon couscous mixture into roasted eggplant shells. Sprinkle with crumbled feta cheese.
08 - Return stuffed eggplants to the oven and bake for 10 minutes until heated through and cheese is lightly golden.
