Preheat oven to 190°C.
Using a very sharp knife, cut a diamond pattern in eggplant flesh. Place the eggplants to a frying pan, the cut side up, and bake for 10 minutes.
Meanwhile, whisk all the ingredients for miso glaze. You might whisk for a while as the miso paste can be quite thick.
Take the eggplant out from the oven and brush their flesh lightly with the miso glaze. Place back in the oven. Bake for additional 10 minutes, until the eggplants become caramelized and slightly brown on the surface.
Prepare your turmeric sauce. Mix all the ingredients in a small bowl until smooth and set aside.
Place the eggplant on a serving dish. Drizzle them with turmeric sauce and sprinkle them with sesame seeds, crushed peanuts, and sliced spring onion. Add halved cherry tomatoes.
Serve immediately. Enjoy!
