Brush the eggplant with olive oil, grill for 2 minutes on each side, until tender and slightly charred.
Drizzle olive oil on cut sides of the bagels. Divide the cut cheese among the bagel bottoms and top with tomato slices and eggplant on top. Season with salt and pepper. Replace the bagel tops.
Bake for 10 to 15 minutes until the cheese has melted and the bagels are starting to toast. Add fresh basil before serving.
