Ingredients

Instructions

  1. Step 1: Pat dry 8 oz fresh tuna steak and season both sides with 1 tsp salt and 1/2 tsp black pepper. Heat 2 tbsp olive oil in a skillet over medium-high heat until shimmering, then sear tuna for 2 minutes per side for rare, or longer to desired doneness, until edges are lightly browned but center remains pink.
  2. Step 2: While tuna cooks, combine 1 diced medium avocado, 1 segmented medium orange, 2 tbsp finely chopped red onion, 1 tbsp lemon juice, 2 tbsp chopped fresh cilantro, 1 small minced jalapeño (seeded), 1/2 diced medium cucumber, and 1/4 cup crumbled feta cheese in a bowl. Gently toss to combine and let flavors meld for 5 minutes.
  3. Step 3: Slice seared tuna into 1/2-inch thick slices and plate. Spoon generous portions of the citrus avocado salsa over and around the tuna. Serve immediately to enjoy the contrast of warm tuna and fresh salsa.
