Cook bacon in a large skillet over medium heat just until the fat is rendered out. Before the bacon begins to brown, remove all but 4 slices of bacon and place in a food processor. Continue to cook the remaining 4 slices until lightly crispy and remove to a paper towel. Keep the bacon fat in the skillet.
Place the buns, cut side down, into the warm bacon fat and toast until golden brown around the edges. Set aside.
Pulse the undercooked bacon in the food processor until it is coarsely ground – approximately 30-45 seconds. Transfer the bacon to a large mixing bowl.
Add the ground beef, Worcestershire sauce, salt and pepper to the bowl and use your hands to gently work the bacon and seasonings into the ground beef.
Divide the meat into 4 portions. Loosely pack each portion to make patties. Then use your thumb to create an indention in the center of each patty.
Preheat the grill and generously oil the grates. Once the grill is hot, place the patties on the grates and cook for 3-5 minutes per side.
Turn off the grill and top each patty with a slice of desired cheese on top. Cover the grill to allow it to melt.
Assemble the burgers and top with one bacon slice cut in half, lettuce, and/or tomato. *Add additional condiments as desired.
