- 1 pound cold salted fresh mozzarella, sliced 1/3 inch thick
- 2 tablespoons balsamic vinegar
- Preheat oven to 400°F with rack in middle.
- Toss tomatoes with 2 tablespoons oil and 1/4 teaspoon each of salt and pepper. Roast tomatoes, cut sides up, in 1 layer in a 4-sided sheet pan until skins are wrinkled and beginning to brown on bottom, about 45 minutes. Cool completely.
