Tuna Salad With Cucumber Ingredients

For the Dressing
• Apple Cider Vinegar or Lemon Juice – Provides acidity to balance the salad; choose based on your flavor preference for this tuna salad with cucumber.
• Olive Oil – Adds richness and helps dress the salad; avocado oil can also be a flavorful substitute.

Step‑by‑Step Instructions for Tuna Salad With Cucumber
Step 1: Prep Your Ingredients
Start by washing and peeling the cucumbers, then chop them into bite-sized pieces, ensuring a crunch in every bite. Next, cut your ripe avocado in half, remove the pit, and scoop the flesh into a bowl, mashing lightly with a fork for a creamy base. Open the canned tuna, drain it well, and flake it into manageable pieces for easy mixing.
Step 2: Combine the Salad Ingredients
In a large mixing bowl, combine the chopped cucumbers, flaked tuna, and mashed avocado. If you choose to include it, finely chop the red onion and add it to the mix for a burst of flavor. For an herbal touch, sprinkle in the fresh dill if available. Stir gently to blend the ingredients while preserving the avocado’s creaminess.
Step 3: Make the Dressing
In a small bowl, whisk together a tablespoon of apple cider vinegar or lemon juice, along with an equal amount of olive oil. Add a pinch of salt, a few cracks of black pepper, and dried oregano if you desire extra flavor. Blend until the dressing is smooth and well-combined, ensuring it will coat the salad evenly.
Step 4: Dress the Salad
Drizzle the prepared dressing over the salad mixture in your large bowl. Gently toss the ingredients using a spatula or wooden spoon to ensure every piece is coated with the zesty dressing. You want a beautiful, vibrant mixture that highlights the freshness of the tuna salad with cucumber without mashing it together.
Step 5: Serve Immediately

Tuna Salad With Cucumber Recipe FAQs
