Creating Tuna Salad Lettuce Wraps is easy if you follow these steps:

1. Prepare the Tuna Salad: In a medium bowl, combine the drained tuna, mayonnaise, Dijon mustard, diced celery, chopped red onion, and lemon juice.
2. Mix Well: Stir until all ingredients are well incorporated. Season with salt and pepper to taste.
3. Prep Lettuce Leaves: Gently wash and dry the lettuce leaves. They should be large and sturdy enough to hold the filling.
4. Assemble the Wraps: Take a lettuce leaf and scoop a generous amount of tuna salad onto the center.
5. Add Toppings: If desired, add sliced avocado, cherry tomatoes, or pickles on top of the tuna salad for extra flavor.
6. Wrap It Up: Carefully fold the sides of the lettuce leaf over the filling to create a wrap.
7. Serve Immediately: Arrange the wraps on a plate for a beautiful presentation.

Making these wraps is so straightforward that you can enjoy them as a meal in no time!
