  • Total Time: 15
  • Yield: 4 servings 1x

Ingredients

Scale

2 cans (5 ounces each) tuna, drained
1 ripe avocado, diced
4 large lettuce leaves (e.g., romaine or butter lettuce), washed and dried
2 tablespoons Greek yogurt
1 teaspoon lime juice
1 tablespoon chopped red onion
1/4 teaspoon salt
1/4 teaspoon black pepper
Optional: chopped cilantro or parsley for garnish

Instructions

In a medium bowl, flake the drained tuna into small chunks.
Add diced avocado, Greek yogurt, lime juice, chopped red onion, salt, and black pepper to the bowl. Gently mix until well combined.
Place lettuce leaves on a serving plate.
Fill each lettuce leaf with the tuna and avocado mixture.
Garnish with cilantro or parsley if desired and serve immediately.

Notes

For best texture, serve immediately after assembling.
You can prepare the components ahead of time and assemble just before serving.
Substitute the red onion with finely diced jalapeño or bell pepper for a different flavor profile.
Leftovers can be stored in the refrigerator for up to 24 hours, though avocado may brown after a while.
