Roasted Eggplant with Tomato and Mint

Preheat oven to 425 degrees. Brush a rimmed baking sheet with 2 tablespoons oil. Arrange eggplant rounds in a single layer and season with salt and pepper. Roast until undersides are browned and release easily from sheet, 25 minutes. Flip each round and season with salt and pepper. Roast until undersides are browned and eggplant is tender, 10 to 12 minutes.

Meanwhile, in a small bowl, mix together 1 tablespoon oil, ricotta salata, capers, onion, tomatoes, mint, and vinegar. Season to taste with salt, pepper, and more vinegar, if desired. Transfer eggplant to a serving platter. Top each round with a spoonful of tomato mixture and serve.
