01 - Preheat a grill or skillet over medium-high heat.
02 - In a bowl, gently combine ground beef with salt, black pepper, and Worcestershire sauce. Shape into four equal patties slightly larger than the buns.
03 - Fry bacon in a pan over medium heat until crispy. Drain on paper towels.
04 - Grill or pan-sear burger patties for 3 to 4 minutes on each side until medium doneness. In the last minute, top each patty with cheddar cheese and cover to melt.
05 - Lightly toast burger buns on the grill or in a toaster.
06 - Spread mayonnaise, ketchup, or Dijon mustard on the bottom buns as desired. Layer lettuce, tomato, and red onion. Add the cheese-topped patty, then avocado slices and crispy bacon. Finish with the top bun.
07 - Serve immediately alongside preferred side dishes.
