Take 4 of the pieces of bacon and place into a chopper or blender and process until all large pieces are ground.
Combine the ground bacon, turkey, applesauce, poultry seasoning, syrup, and salt and pepper in a large bowl. Use your hands to get it mixed well. Form into 4 equally sized patties.
Fire up your grill for direct and indirect cooking.
Brush one side of the patties with olive oil and place over direct heat. Brush tops with oil.
Grill until lightly charred. Flip and grill another 3-4 minutes.
Remove to indirect heat and continue cooking until internal temperature reaches 170 F.
Lightly toast the buns.
Serve patties on toasted buns slathered with the sauce, topped with your favorite toppings and the remaining bacon slices.
