Ingredients

  • 1/2 cup extra-virgin olive oil
  • 1 pound zucchini, halved lengthwise and thinly sliced
  • 1 red bell pepper, cut into thin strips
  • 1/2 small red onion, thinly sliced
  • 4 thyme sprigs
  • 4 garlic cloves2 thinly sliced, 2 halved
  • Salt and freshly ground pepper
  • 1 tomato, coarsely chopped
  • 1 small fennel bulbhalved, cored and sliced paper-thin
  • 1/4 cup pitted kalamata olives, coarsely chopped
  • 1 tablespoon drained capers
  • Four 5-ounce tuna steaks, cut 1 inch thick

Method

  • In a large, deep skillet, heat 1/4 cup of the olive oil.
  • Add the zucchini, bell pepper, onion, thyme and sliced garlic and season with salt and pepper.
  • Cook over high heat, stirring occasionally, until the vegetables are crisp-tender, about 7 minutes.
  • Add the tomato, fennel, olives and capers, season with salt and pepper and cook, stirring, until the vegetables are tender, 2 to 3 minutes longer.
  • Discard the thyme.
  • In a medium skillet, heat the remaining 1/4 cup of oil with the halved garlic cloves.
  • Season the tuna with salt and pepper, add it to the skillet and cook over moderate heat for 3 minutes, turning once.
  • Cover the skillet and cook the tuna over very low heat for 2 minutes longer; the tuna should still be slightly rare in the center.
  • Spoon the vegetables onto plates.
  • Top with the tuna steaks and the browned garlic halves and serve.
