Cook the Turkey Bacon
In a skillet over medium heat, cook the turkey bacon until golden and crisp. Transfer to a paper towel-lined plate to drain excess grease.

Toast the Croissants (Optional)
Slice the croissants in half lengthwise. Lightly toast them in a skillet or oven for a warm, slightly crispy texture.

Spread the Condiments
Mix mayonnaise and Dijon mustard. Spread evenly on both halves of the croissants to coat.

Layer the Ingredients
On the bottom half of each croissant, layer lettuce, turkey, ham, cheeses, tomato slices, and turkey bacon. Sprinkle a pinch of salt and pepper.

Close and Press
Add another lettuce leaf on top, then close the sandwich with the croissant top. Press gently to secure the layers.

Slice and Serve
Use a serrated knife to cut each sandwich in half. Serve immediately or wrap for on-the-go enjoyment.
