Preheat grill pan to high heat. Then spray zucchini slices with olive oil and season with salt and pepper. Place the zucchini slices on the grill pan and grill for 5 minutes, flipping half way through. Remove from grill pan.
Begin to layer the panini; with the slices of cooked grilled zucchini, fresh mozzarella, basil, and sliced tomatoes. Repeat the same steps for the second panini. Place in a panini press and cook for 10 minutes on medium-high heat or until the bread is toasted and the cheese is melted. Enjoy immediately.
