Cook the pasta according to the package directions. Heat the oil in a large nonstick skillet over medium-high heat. Add the eggplant, 1/2 teaspoon salt, and 1/2 teaspoon pepper and cook, stirring occasionally, until golden brown, about 8 minutes. Stir in the garlic and tomatoes and cook, stirring occasionally, until the tomatoes begin to soften, 3 to 4 minutes. Add the cooked pasta and mint and toss. Divide among individual bowls and top with the grated cheese.
