Roast the Eggplants: Preheat your oven to 400°F. Cut the eggplants in half lengthwise and score the flesh deeply in a crosshatch pattern, being careful not to pierce the skin. Lay the eggplants cut-side up on a baking sheet, drizzle with olive oil, and season with ½ teaspoon of the salt and ¼ teaspoon of the black pepper. Roast in the oven for 20 minutes until softened.
Mix the Filling: While the eggplants roast, combine the chickpeas, cauliflower rice, pine nuts, Parmesan cheese, lemon juice, garlic, cumin, coriander, paprika, thyme, and the remaining ½ teaspoon salt and ¼ teaspoon black pepper in a medium bowl. Stir the mixture until it’s evenly combined.
Fill the Eggplants: Take the roasted eggplants out of the oven and evenly distribute the chickpea and cauliflower mixture over the top, pressing it gently into the scored flesh. Return the eggplants to the oven and roast for an additional 10–15 minutes, or until the filling is lightly browned and the eggplants are tender.
Prepare the Turmeric Tahini: In a small bowl, mix the tahini sauce with turmeric and cayenne pepper until smooth and well blended.
Finish and Serve: Drizzle the turmeric tahini sauce over the stuffed eggplants, and garnish with fresh thyme before serving.
