Ingredients

  • 1/3 cup extra-virgin olive oil
  • 1/4 cup balsamic vinegar
  • 6 garlic cloves, chopped
  • 1 tablespoon chopped fresh rosemary
  • 1 teaspoon (packed) finely grated orange peel
  • 1/2 teaspoon dried crushed red pepper
  • 4 large heads of radicchio, each quartered through core end
  • 1 cup Pecorino Romano cheese shavings

Method

  • Whisk oil, vinegar, garlic, rosemary, orange peel, and crushed red pepper in large bowl. Add radicchio and toss to coat. Marinate 15 minutes.
  • Prepare barbecue (medium heat). Drain marinade into small bowl. Place radicchio on grill; sprinkle with salt and pepper.
