2 1/4-pound eggplant, sliced crosswise 1 inch thick

1/2 pound buffalo mozzarella, sliced 1/4 inch thick
8 basil leaves, torn
Coarse sea salt
How to Make It
Light a grill. Brush the bread on both sides with olive oil and grill over high heat until crisp on the outside but still soft inside, about 30 seconds per side. Transfer to a platter.
Brush the eggplant slices with olive oil and season generously with salt and pepper. Grill over moderate heat until charred on the bottom, about 5 minutes. Turn and grill until tender, about 3 minutes longer.
Top the eggplant with the tomato, mozzarella and basil. Cover the grill and cook until the cheese melts, 2 minutes. Transfer the eggplant to the bread, sprinkle with sea salt and serve.
