Place your lettuce on a cutting board and carefully cut 2 slices to create the lettuce buns as shown.
If it feels too thick or too dense, you can remove a few of the center pieces until it's just right for you.
Slice your tomato and red onion, and get all the remaining ingredients together.
To assemble: add a spoonful or two, of homemade ranch dressing on top of one side of your lettuce "bun.
Top with turkey slices, cheese, tomatoes, and onion to your liking.
Place crispy bacon on top, then sandwich the whole thing with the second lettuce "bun". Serve immediately and enjoy!
