In a small bowl, stir together the mayonnaise, chopped dill pickle, and whole-grain mustard until well combined.
Place 2 lettuce leaves on a clean work surface, slightly overlapping them to create a sturdy base.
Spread about 1 tablespoon of the mayonnaise mixture evenly over the lettuce leaves.
Layer 3 ounces of sliced turkey on top.
Add 1 ounce of sliced sharp Cheddar cheese.
Place 2 tomato slices over the cheese.
Carefully roll the lettuce into a tight wrap.
Cut the wrap in half if desired.
Repeat with the remaining ingredients to make four Turkey & Cheddar Lettuce Wraps.
Serve immediately or refrigerate until ready to enjoy.
