Preheat oven to 375 F.

On large baking sheet, place bread slices and brush with 1 Tbsp olive oil on both sides, and then set aside.

In large cast iron skillet or glass baking dish, combine tomatoes, olive oil, and garlic. Roast in preheated oven for 15 to 20 minutes, until tomatoes burst. Transfer to large bowl, discard garlic clove, and cool for 10 minutes.

Meanwhile, toast bread in oven for about 10 minutes, until golden brown, flipping once halfway through. Keep an eye on bread, as ovens can range in how quickly they toast.

To roasted tomatoes, gently stir in remaining ingredients except for cheese. Add toasted bread to serving platter and top with tomato mixture, followed by torn mozzarella, additional basil, and black pepper. Serve immediately.
