Grilled Tomatoes with Oregano and Lemon

Heat a grill to medium-high. In a small bowl, combine garlic, lemon zest, lemon juice, oregano, and 2 tablespoons olive oil. Season with salt and pepper. Clean and lightly oil hot grill. Halve tomatoes crosswise and brush cut sides with 2 tablespoons oil. Place, cut side down, on grill. Grill until lightly charred, about 4 minutes. With a metal spatula, flip tomatoes and grill until skins blister and begin to char, 2 to 3 minutes. Transfer tomatoes to a serving platter, season with salt and pepper, and drizzle with oregano-lemon oil. Serve tomatoes warm or at room temperature.
