Ingredients

1 can (5 oz) tuna in water, drained
1 large cucumber, diced
¼ cup red onion, finely chopped
¼ cup mayonnaise or Greek yogurt
1 tablespoon olive oil
1 tablespoon lemon juice
½ teaspoon salt
¼ teaspoon black pepper
½ teaspoon garlic powder
1 tablespoon chopped fresh dill or parsley

Substitution Notes:

You can use canned tuna in oil for extra richness or light mayo for a lower-calorie version.
Substitute Greek yogurt for mayonnaise if you want a tangier flavor and added protein.
Add chopped celery or green onions for extra crunch.
Use lime juice instead of lemon for a brighter flavor twist.

Step-by-Step Instructions

Step 1: Prepare the ingredients

Wash and dice the cucumber into small, even cubes so it mixes easily with the tuna. Finely chop the red onion and herbs. Drain the canned tuna thoroughly to remove excess moisture, ensuring the salad stays crisp instead of watery.

Step 2: Mix the dressing

In a medium bowl, combine mayonnaise (or Greek yogurt), olive oil, lemon juice, garlic powder, salt, and black pepper. Whisk the dressing until it’s smooth and creamy. Taste and adjust seasoning as needed for balance between creaminess and acidity.

Step 3: Combine everything

Add the drained tuna, diced cucumber, red onion, and herbs to the bowl with the dressing. Gently fold the mixture using a spatula or spoon until all ingredients are coated evenly. Avoid overmixing to keep the texture light and fluffy.

Step 4: Chill and serve

For the best flavor, refrigerate the salad for 20–30 minutes before serving. This allows the dressing to absorb into the cucumbers and tuna, enhancing freshness and taste. Serve chilled as a main dish, light lunch, or side salad.

How to Serve

As a light meal: Serve chilled in a bowl with a sprinkle of extra herbs and cracked black pepper on top.
With toast or crackers: Spread on whole-grain toast or serve with crisp crackers for a quick lunch or snack.
In lettuce wraps: Spoon the salad into romaine or iceberg lettuce leaves for a low-carb, fresh presentation.
With grains: Serve over cooked quinoa, brown rice, or couscous to make it a complete meal.
As a side dish: Pair with grilled fish, roasted chicken, or vegetable soup for a balanced dinner.
In sandwiches: Layer between slices of sourdough or pita bread for an easy on-the-go option.

Additional Tips

Chill the tuna and cucumber before mixing for a colder, crisper texture.
Use an English cucumber or seedless cucumber for the best balance of crunch and flavor.
For a creamier salad, add an extra spoon of mayonnaise or Greek yogurt.
Always taste before serving and adjust salt, pepper, or lemon juice to your liking.
To enhance flavor, mix in a teaspoon of Dijon mustard or a few drops of hot sauce.
Store the salad in an airtight container and stir before serving again to redistribute the dressing.
