Ingredients

For the Tuna Salad

• 2 cans (5 oz / 142 g each) tuna in water or olive oil, drained
• 2 ripe avocados, diced
• 1 cup (150 g) sweet corn, drained
• 1 cup (150 g) cherry tomatoes, halved
• 1/2 small red onion, finely diced
• 1/2 cup (75 g) cucumber, diced
• 2 tbsp fresh cilantro or parsley, chopped
• 1 tbsp fresh jalapeño, finely chopped, optional
• 1/4 tsp salt
• 1/4 tsp black pepper

For the Creamy Lime Dressing

• 1/3 cup (80 g) Greek yogurt
• 2 tbsp fresh lime juice
• 1 tbsp olive oil
• 1 tsp honey
• 1 small garlic clove, minced
• 1/2 tsp Dijon mustard
• 1/4 tsp salt
• 1/4 tsp black pepper
• 1–2 tbsp water, as needed

For Garnishing

• 1 tbsp fresh cilantro or parsley
• Lime wedges
• 1/4 tsp red pepper flakes, optional

How to Make It

1. Prepare the Tuna

Drain the tuna thoroughly and transfer it to a large mixing bowl. Gently flake it with a fork, keeping some small pieces intact for a pleasant texture. Avoid overmixing the tuna.

2. Prepare the Vegetables

Halve the cherry tomatoes, dice the avocados and cucumber, and finely chop the red onion. If using jalapeño, remove the seeds if desired and chop it finely.

Try to keep the avocado pieces reasonably large so they hold their shape when the salad is mixed.

3. Make the Creamy Lime Dressing

In a small bowl, whisk together the Greek yogurt, fresh lime juice, olive oil, honey, minced garlic, Dijon mustard, salt, and black pepper.

Add 1–2 tablespoons of water, a little at a time, until the dressing reaches a smooth and pourable consistency.

4. Combine the Salad

Add the flaked tuna, diced avocado, sweet corn, cherry tomatoes, cucumber, red onion, cilantro or parsley, and optional jalapeño to a large bowl.

Make sure the ingredients are distributed evenly without crushing the avocado.

5. Add the Dressing

Pour the creamy lime dressing over the tuna and vegetable mixture. Use enough dressing to lightly coat everything without making the salad overly wet.

6. Toss Gently

Using a large spoon or spatula, carefully fold the ingredients together. Work gently so the avocado pieces remain mostly intact and the tuna keeps its texture.

7. Chill

Cover the bowl and refrigerate for 10–15 minutes. This short resting time allows the flavours to come together while keeping the vegetables fresh and crisp.

8. Garnish

Transfer the salad to a serving bowl or platter. Sprinkle with fresh cilantro or parsley and optional red pepper flakes. Serve with fresh lime wedges for an extra burst of citrus flavour.

9. Serve

Serve chilled on its own, over crisp lettuce, with toasted bread, or spooned into wraps and sandwiches. It also makes a convenient filling for avocado halves or lettuce cups.

Why This Recipe Works

This tuna salad combines several textures and flavours in one simple dish. Flaky tuna provides a savoury, satisfying base, while ripe avocado adds creaminess without needing a heavy dressing.

Sweet corn and cherry tomatoes bring natural sweetness and freshness, while cucumber adds a crisp element. Red onion and optional jalapeño provide a little extra bite, while fresh herbs brighten everything up.

The creamy lime dressing is what brings all the ingredients together. Greek yogurt creates a smooth base, lime juice adds brightness, honey provides a subtle sweetness, and Dijon mustard and garlic give the dressing a savoury finish.

Tips for the Best Avocado Tuna Salad

• Drain the tuna well: Excess liquid can make the salad watery and dilute the dressing.
• Use ripe but firm avocados: They should be creamy but still firm enough to hold their shape when mixed.
• Cut the vegetables evenly: Similar-sized pieces make every bite more balanced.
• Add the dressing gradually: Start with most of the dressing and add more if needed.
• Be gentle with the avocado: Fold the ingredients instead of aggressively stirring them.
• Use fresh lime juice: Fresh lime gives the dressing a brighter and more refreshing flavour.
• Chill briefly: A short rest in the refrigerator helps the flavours blend while keeping the vegetables crisp.

Serving Suggestions

This salad is delicious served on a bed of crisp lettuce for a light lunch. It can also be spooned into tortillas or wraps with extra greens for an easy handheld meal.

For a simple serving, pair it with toasted sourdough, whole-grain bread, crackers, or a side of fresh fruit. It also works well as a filling for sandwiches or lettuce cups.

Frequently Asked Questions

Can I use tuna packed in water?

Yes. Tuna packed in water works very well and gives the salad a lighter flavour. Tuna packed in olive oil can also be used if you prefer a richer taste.

Can I make this salad ahead of time?

You can prepare the tuna, vegetables, and dressing ahead of time, but for the freshest texture, combine everything shortly before serving. The avocado is best when freshly cut.

How can I prevent the avocado from browning?

Fresh lime juice helps slow browning, and keeping the salad chilled also helps maintain its colour. For the best appearance, prepare the avocado shortly before serving.

Can I use mayonnaise instead of Greek yogurt?

Yes. Mayonnaise can be substituted for Greek yogurt if you prefer a richer and creamier dressing. You may want to adjust the amount of lime juice to taste.

Can I add more vegetables?

Absolutely. Bell peppers, celery, shredded carrots, radishes, or chopped lettuce can all work well in this salad while adding extra crunch and colour.

How should I store leftovers?

Store leftovers covered in the refrigerator and enjoy them promptly. Because the salad contains avocado and fresh vegetables, the texture and colour are best when eaten soon after preparation.
