Line a rimmed baking sheet with aluminum foil and preheat oven to 400° F.

Cut tomatoes into four slices each. Spread tomato slices out on baking sheet.

Sprinkle tomatoes with white balsamic vinegar, grated Parmesan cheese, dried basil, Kosher salt and pepper.

Bake for 15-17 minutes, or until cheese has melted and tomatoes are soft around the edges.
