Preheat oven to 400 degrees F. Spray a baking sheet with cooking spray and set aside.
Cut tomato into thick slices and season with salt and pepper.
In a small bowl, whisk eggs and water. Pour breadcrumbs onto a large dish.
One at a time, dip the tomatoes into the egg mixture and then into the breadcrumbs, allowing the excess to drip off. Place each tomato onto the baking sheet.
Bake for 20-25 minutes, flipping half way through. After you flip the tomatoes, top each with a sprinkle of Parmesan cheese. Continue cooking until done or until cheese is melted and tomatoes are crispy.
