Slice the eggplant into ¼-inch rounds and arrange in a single layer on the cookie sheet.
Whisk together remaining ingredients and pour over eggplant. Flip the slices so that both sides are coated.
Turn oven to 400 and wait for it to preheat (allowing the eggplant to marinate in the meantime).
Bake 10-15 minutes, until very brown. Flip and bake another 5-10 minutes.
