Prepare the dressing by whisking all the ingredients together. Taste and adjust to perfection.
Thoroughly wash the shiitake caps and squeeze them hard to let the excess water out.
In a small pan, heat 2 tbsp of cooking oil to medium high and fry the shiitake caps for 2-3 minutes until they just turn golden. Transfer onto a paper towel.
Add 1/2 cups of oil to the same pan. Deep fry garlic slices for about 20-30 seconds, until they start turning deep golden. Immediately take them out with a blotted spoon and transfer to a paper towel.
Cut the eggplant into halves lengthwise. Make a few criss-cross cuts on the open side and season with a little salt.
Heat the remaining oil in a large pan to medium high.
Fry the eggplant halves skin side down for 4-5 minutes, then flip, lower the heat, put a lid on and cook for another 4-5 minutes until the flesh softens.
Transfer the eggplants to a serving plate cut size up.
Drizzle over 1/2 of the dressing and leave for a few minutes for the flavours to impart.
In the meantime, combine shiitake caps, coriander leaves and sesame seeds and toss with the remaining dressing.
Fluff the eggplant flesh with a fork and scoop the mushroom & coriander mixture over.
Scatter over garlic chips and serve immediately.
