Meanwhile, heat the olive oil in a large skillet over medium heat. Whack the garlic cloves with the side of a knife and add them to the hot oil. Cook, shaking the skillet, until the garlic is lightly browned, about 3 minutes. Lower the work bowl with the tomatoes close to the skillet and carefully — they will splatter — slide the tomatoes into the pan. Bring to a boil, season lightly with salt and generously with crushed red pepper, and boil 2 minutes.
