Ingredients

Instructions

  1. Step 1: In a medium bowl, mix 8 oz finely diced sushi-grade tuna with 2 tbsp soy sauce, 1 tsp sesame oil, and 2 thinly sliced green onions. Stir gently to combine and refrigerate for 10 minutes to marinate.
  2. Step 2: In a separate bowl, mash 1 medium diced avocado with 1 tsp wasabi paste, 1 tbsp lime juice, 1/4 tsp salt, and 1/8 tsp black pepper until smooth but slightly chunky.
  3. Step 3: To serve, place a ring mold on a chilled plate and add half the avocado mixture, pressing down gently. Top with half the marinated tuna mixture, pressing lightly to hold shape. Carefully remove the ring mold.
  4. Step 4: Sprinkle 1 tsp toasted sesame seeds and garnish with microgreens. Repeat for remaining portions and serve immediately.
