Grilled Hearts Of Romaine - cooking recipe

Ingredients

3 romaine lettuce hearts, halved lengthwise
1 tablespoon olive oil, divided, or as needed
2 tablespoons freshly grated Parmigiano-Reggiano cheese, or to taste
2 tablespoons balsamic vinegar, or to taste
2 tablespoons sherry vinegar, or to taste
2 tablespoons olive oil, or to taste

Preparation

Preheat an outdoor grill for high heat, and lightly oil the grate.
Brush each romaine lettuce half with 1/2 teaspoon olive oil.
Cook romaine hearts, cut-side down, on the preheated grill until the cut-side is slightly caramelized but the inside is still cool and crisp, about 2 minutes. Transfer lettuce, cut-side up, to a platter. Sprinkle Parmigiano-Reggiano cheese over lettuce and drizzle balsamic vinegar, sherry vinegar, and 2 tablespoons olive oil over the top.
