Instructions

  1. Step 1: Bring a large pot of salted water to a boil, add 200g pasta, and cook for 8-10 minutes until al dente, with a slight bite to the tooth. Drain the pasta, reserving 1/2 cup of the pasta water in case you need it later for adjusting consistency. Tip: Use the reserved pasta water to help emulsify the dressing if the mixture becomes too dry.
  2. Step 2: In a medium bowl, use a fork to flake 150g canned tuna into small, even pieces, then mash 1 medium avocado with the fork until smooth but not over-processed, ensuring no large chunks remain. Tip: Add the juice of 1 lemon (about 2 tbsp) to the avocado to prevent browning and enhance flavor.
  3. Step 3: Finely dice 1 small red onion into 1/4-inch cubes, then add to the bowl with the tuna and avocado. Squeeze the remaining juice of 1 lemon (about 2 tbsp) over the mixture and toss gently to combine, ensuring the onion is evenly distributed. Tip: Avoid over-mixing the avocado to maintain a creamy texture.
  4. Step 4: Add 2 tbsp olive oil to the bowl and toss thoroughly to coat all ingredients evenly. Season with salt and pepper, tasting and adjusting as needed. Tip: For a richer flavor, add a pinch of dried oregano or a drizzle of extra virgin olive oil just before serving.
