Cut the eggplant into 1/2" thick circles.
Combine the rest of the ingredients in a small saucepan and bring to a boil, cook until it reduces to a glaze, careful not to over do it.
Taste and adjust seasoning.
Lay out the eggplant on a baking sheet lined with parchment. Brush on the glaze and broil until well caramelized.
Remove to a plate and serve hot or cold, sits well in the fridge for at least a week.
