Preheat the oven to 180C(fan)/350F/Gas Mark 4.
Wash and dry aubergines (eggplants) and cut them in half lengthwise leaving the top intact (mostly for presentation).
Next, using a sharp knife, score each half of the aubergine with criss cross incisions. They should be deep but not all the way through as to cut the skin. Repeat with all remaining aubergine halves.
In a small bowl mix/whisk together miso, soy sauce/tamari, tahini, rice vinegar, sesame oil and maple syrup (or other sweetener of choice).
Mix them until you get nice and glossy glaze (consistency of natural peanut butter).
Line the baking sheet with some greaseproof paper and place scored aubergine halves on top.
Using pastry brush or a spoon brush/spread miso glaze generously over all the aubergine halves, making sure you get miso mixture into all the incisions.
Sprinkle over some sesame seeds and bake in the preheated oven for 30-40 minutes until aubergine (eggplant) halves collapse and brown on top and the flesh is really soft and squidgy.
Serve immediately with plenty of sliced spring onions on top and enjoy!
