Ingredients

Instructions

  1. Step 1: Drain 2 cans (5 oz each) canned tuna in water thoroughly, then flake with a fork into a medium bowl. Cut 1 avocado in half, remove pit and peel, then mash the flesh with a fork until smooth.
  2. Step 2: Add 1/4 cup finely diced red onion, 2 finely diced celery stalks, 2 tbsp finely chopped fresh dill, 2 tbsp extra-virgin olive oil, 1/2 tsp kosher salt, and 1/4 tsp black pepper to the mashed avocado. Stir until combined, then fold in the flaked tuna until evenly distributed.
  3. Step 3: Juice 1 lemon to get 2 tbsp juice, then add to the tuna mixture along with the zest of 1/2 lemon. Mix gently until all ingredients are coated and the salad has a creamy texture without being runny.
  4. Step 4: Divide 6 cups butter lettuce among plates. Top with 1.5 cups tuna salad per serving. For best results, serve immediately to prevent the avocado from browning.
