01 - In a large bowl, combine ground turkey, finely chopped onion, minced garlic, Dijon mustard, Worcestershire sauce, salt, black pepper, breadcrumbs, and egg. Mix gently until just combined.
02 - Shape the mixture into 4 equal-sized patties for uniform cooking.
03 - Heat 1 tablespoon olive oil in a skillet over medium heat. Cook the patties 5 to 6 minutes per side until golden brown and fully cooked. In the last minute, place a slice of cheddar cheese on each patty and cover to melt.
04 - In a separate pan, cook bacon slices until crisp. Drain excess fat on paper towels.
05 - Wipe out bacon pan, add a bit of oil or butter, and fry eggs sunny-side up or to preferred doneness. Season with salt and pepper.
06 - Lightly toast brioche burger buns until golden.
07 - Mix mayonnaise with hot sauce if using, then spread evenly on the cut sides of each bun.
08 - On the bottom bun, layer lettuce and tomato, top with the turkey patty with melted cheese, avocado slices, two bacon strips, and a fried egg. Cover with the top bun.
09 - Serve the burgers immediately while warm.
