Preheat the grill to 375F. Make sure that you can do both direct and indirect cooking.
Mix the ground beef, Worcestershire sauce, salt, pepper, garlic powder, and minced onion. Use a scoop for form even balls. Roll them then flatten each ball into a somewhat flattened burger patty shape.
Use a cast iron skillet. Place it over the indirect heat then cook the bacon. Do not make it too crisp, or you won’t be able to skewer it. Set the bacon aside then remove the grease.
Place the skillet back over indirect heat then add the burger patties. Cook through, turning halfway. Place the skillet over direct heat then sear both sides. After flipping to the second side add a slice of cheese and melt over each. Set the burgers aside.
Use large skewers to stack the burger patties, bacon, lettuce, tomatoes, and pickle slices. You should end up with two patties per skewer.
Mix the mayonnaise, ketchup, mustard, minced onion, minced pickle, and pickle juice. Serve along with the kebabs.
