1) Slice the eggplant into 1/4-inch thick slices. Place the eggplant
slices on a paper towel and season with salt; set aside about 30
minutes.
This will help draw some of the moisture out of the eggplant. Pat the
eggplant dry with paper towels.
2) Preheat panini grill. Lightly spritz eggplant with olive oil, season
with salt and pepper.
When the grill is hot, grill eggplant about 7-8 minutes, turning once
half way through. Set aside.
3) Slice the bread open and place 3 slices of grilled eggplant, 1 slice
of mozzarella, 1/2 tablespoon of pesto, and 2 slices of tomatoes on each
sandwich.
4) Close and lightly spray the top of the bread with oil. Place on a
panini press and close until the cheese melts and the bread is toasted.
Cut in half diagonally and eat immediately.
