Ingredients

Instructions

  1. Step 1: Pat dry 8 oz ahi tuna steak and season both sides with 1 tsp sea salt and 1/2 tsp black pepper. Heat 2 tbsp olive oil in a skillet over high heat until shimmering, then sear tuna for 1.5 minutes per side for medium-rare, creating a golden crust while keeping the center pink. Remove and let rest.
  2. Step 2: Dice 1 medium ripe avocado and combine with 1/2 cup diced cucumber, 2 tbsp finely chopped red onion, 2 tbsp chopped fresh parsley, and 1 tbsp chopped fresh mint in a bowl. Add 1 tbsp fresh lemon juice and gently toss to combine, allowing flavors to meld.
  3. Step 3: Slice seared tuna into 1/4-inch thick slices and arrange on a plate. Spoon the avocado-cucumber salsa over the tuna, sprinkle with 1/4 cup feta cheese crumbles and 2 tbsp toasted pine nuts for crunch and tang, serving immediately.
