Combine the cream cheese and Greek yogurt in a small bowl.
Use a hand mixer or small whisk to whip the two together, creating a small smooth spread.
Stir in the salt.
Gently spread the cream cheese mixture over half of the inside of the lettuce leaf.
Layer on the bacon, sun-dried tomatoes, pepper jack slices, avocado, and turkey.
Tightly roll the lettuce around the fillings, slice in half, and serve!
