Place the ground beef and onion in a skillet over medium high heat, and saute until the meat is browned and the onions have softened.
Drain the excess grease.
Add 2 Tbsp. dill pickle relish, worcestershire sauce and salt and pepper to taste to the skillet, and saute until well combined.
In a bowl, stir together the mayonnaise, 1 tbsp dill pickle relish, Swerve and sugar free ketchup until well combined.
Preheat the oven to 400 degrees.
Arrange the cheese in circles about 3-4 inches across on a parchment lined baking sheet,
Bake for 6-8 minutes until the edges of the cheese circles start to brown and turn crispy.
Remove the baking sheet from the oven, and immediately place a line of sauce down the center of each cheese circle.
Sprinkle lettuce on top of the sauce.
Add some meat mixture down the center of the cheese circles.
Quickly roll the cheese circles up around the filling. Allow the cheese to cool so that it hardens, and then serve.
