In a small bowl, combine spices.
Preheat oven to 200°C and line a baking tray. Slice eggplants in half lengthwise and score the flesh in criss-cross patterns. On lined tray place eggplant, spray with olive oil and sprinkle with half of the spice mix. Bake for 20-25 minutes while you prepare the filling.
In a large frying pan, heat olive oil over medium-high. Add onion, remaining spice mix, garlic and mince and cook until mince is browned, about 10 minutes. Add cherry tomatoes and cooked rice and cook, stirring often, for another 5 minutes. Remove pan from heat and add spinach. Stir to combine spinach and mince and set aside.
In a bowl, combine tahini sauce ingredients. Set aside until ready to serve. (Thin the sauce with a tablespoon or two of water if desired).
Remove eggplant halves from oven and scoop out the majority of the flesh. Stir into the mince mixture then divide between the eggplant shells. Place back in the oven for 5 minutes.
Serve stuffed eggplants on a bed of mesclun and drizzle over tahini sauce. Garnish with pomegranate seeds and mint.
