Ingredients

  • 1 tablespoon fresh lime juice
  • 1 tablespoon fresh marjoram or oregano (or 1 teaspoon dried)
  • 4 tablespoons olive oil
  • 1 1/2 pounds fresh tuna in one thick piece
  • 1 tablespoon cracked black pepper
  • 2 tablespoons canola oil
  • 1 pound fresh spinach, well rinsed, dried and trimmed of heavy stems
  • 1 cup cooked white beans (cannel- lini beans)
  • Salt and freshly ground black pepper to taste

Method

  • Beat the lime juice, marjoram and 2 tablespoons of the olive oil together.
  • Set aside.
  • Trim any dark areas from the tuna, then cut it into four equal pieces, trimming them a little if necessary to make four rectangular logs.
  • Press the cracked black pepper over the outside of the pieces of fish.
  • Heat all but a teaspoon of the remaining olive oil plus the canola oil in a large, heavy skillet.
  • When the oil is very hot, carefully place the fish in the skillet (to avoid splattering) and sear each piece for barely a minute, then turn and continue to sear the fish pieces briefly on each of the remaining three sides.
  • Remove the fish to a warm plate.
  • The fish should be rare in the middle.
  • Wipe out the skillet and add the remaining olive oil.
  • Add the spinach and saute it for a few minutes, until the spinach is barely wilted.
  • Add the beans, season with salt and pepper and continue to saute until the spinach is wilted but is still a bright green and the beans are completely heated through.
  • Divide the spinach mixture equally among four dinner plates.
  • Cut the blocks of seared tuna into slices one-half-inch thick and array the slices on top of the spinach.
  • Briefly beat the vinaigrette, then drizzle the vinaigrette around the tuna and the spinach.
  • The plates are now ready to be served.
