Ingredients

  • ¾ lb Italian fry peppers (light green)
  • 2 piece sushi-grade tuna steaks
  • teaspoons salt
  • 1 teaspoon black pepper
  • tablespoons fresh lemon juice
  • ½ teaspoon Dijon mustard
  • ¼ cup olive oil
  • tablespoons small capers
  • 2 tablespoons fresh flat-leaf parsley

Cooking Instructions

  1. 1.

    Prepare gas grill for cooking over direct high heat.

    5 min

  2. 2.

    While grill heats, cut peppers lengthwise into quarters, discarding stems and seeds. Trim ends so that quarters lie flat.

    5 min

  3. 3.

    Sprinkle tuna all over with 1 teaspoon salt and 1/2 teaspoon pepper. Cook tuna and peppers on lightly oiled grill rack, turning over once, until tuna is pink only in center and peppers are just tender, 4 to 6 minutes total (peppers may take longer than tuna). Transfer tuna and peppers as cooked to a serving plate.

    6 min

  4. 4.

    While tuna cooks, whisk together lemon juice, mustard, and remaining 1/4 teaspoon salt and 1/2 teaspoon pepper in a small bowl, then add oil in a slow stream, whisking until emulsified. Whisk in capers and parsley.

    5 min

  5. 5.

    Serve tuna topped with peppers and caper vinaigrette.
