Preheat the oven to 350° F. Slice the eggplants in half lengthways and score the flesh in a diamond pattern, taking care not to cut through the skin. Line a baking sheet with greaseproof paper and lay the eggplants on top, cut sides up.
Mix the miso, honey, soy sauce, sesame oil, ginger and garlic with 2-3 tablespoons of water to make a smooth paste. Brush over the eggplant flesh and roast for 20-25 minutes until golden brown and soft. Sprinkle with the spring onions and sesame seeds and serve over Cashewgurt®.
