Grilled-Eggplant Parmesan

Preheat grill to medium-high. Brush cut sides of tomatoes and shallot with 1 tablespoon oil. Grill, cut-side down, until charred in spots, 4 to 5 minutes. Flip and continue cooking until vegetables soften slightly, 2 to 3 minutes more. Transfer to a cutting board. When cool enough to handle, roughly chop and transfer to a bowl; season with salt and pepper.

Brush both sides of eggplants with remaining 3 tablespoons oil; season with salt and pepper. Grill, turning once, until lightly charred in places and almost tender, 4 to 5 minutes per side. Transfer to a plate.

Top eggplants with mozzarella. Return to grill and cook, covered, until cheese melts, 1 to 2 minutes. Top evenly with tomato mixture, sprinkle with basil, drizzle with oil, and serve with torn rustic bread.
