Ingredients

• 1 can (5 oz) canned tuna in water (drained)
• 2 tablespoons mayonnaise
• 1 teaspoon sriracha sauce
• 1 tablespoon green onion (finely chopped)
• 2 tablespoons celery (finely diced)
• 1 teaspoon lemon juice
• 0.5 teaspoon garlic powder
• 0.25 teaspoon salt
• 0.25 teaspoon black pepper
• 6 leaves romaine lettuce leaves (or other large-leaf lettuce)
• 1 medium avocado (sliced)
• 1 small jalapeno (optional, thinly sliced)

Directions

Step 1

In a medium mixing bowl, combine the drained tuna, mayonnaise, sriracha sauce, green onion, celery, lemon juice, garlic powder, salt, and black pepper. Mix thoroughly until all ingredients are well incorporated.

Step 2

Taste the mixture and adjust the seasoning, adding more salt, pepper, or sriracha if desired for additional flavor or heat.

Step 3

Lay out the romaine lettuce leaves on a clean surface. You’ll need three leaves per sandwich to create a sturdy base and wrap.

Step 4

Divide the tuna mixture evenly among the lettuce leaves, spooning it into the center of each set of three leaves.

Step 5

Top the tuna mixture with avocado slices and, if desired, a few thin slices of jalapeno for extra spiciness.

Step 6

Fold the sides of the lettuce leaves over the filling gently to create a wrap-like sandwich. Secure with toothpicks if necessary.

Step 7

Serve immediately or wrap tightly for a portable meal. Enjoy!
