• Mix well until all ingredients are evenly incorporated. Season with salt and pepper to taste.

• Assemble the Wraps Lay out the lettuce leaves on a clean work surface.
• Spoon the tuna salad mixture evenly onto each lettuce leaf, spreading it out to cover the surface.

Step 3:

• Roll the Wraps Carefully roll up each lettuce leaf with the tuna salad mixture inside, creating a tight wrap.
• Secure the wraps with toothpicks if necessary.

Step 4:
