Preheat the oven to 200°C. Cut the eggplant into slices about 1/2 cm thick. Arrange on a baking sheet lined with parchment paper.
In a small bowl, mix the marinade ingredients, then use a pastry brush to coat the eggplant on one side, flip it over, and brush with marinade again. Flip once more and continue coating the eggplant until the marinade is used up.
Place in the oven and bake for about 25 minutes. Eggplant prepared this way can be used as a sandwich topping, for example with tomato, lettuce and/or avocado, and mayonnaise or hummus.
