01 - In a large bowl, combine ground turkey, chopped onion, minced garlic, Dijon mustard, Worcestershire sauce, salt, black pepper, breadcrumbs, and one egg. Mix gently until just combined.
02 - Form the mixture into four equal patties, ensuring an even thickness for uniform cooking.
03 - Heat 1 tablespoon olive oil in a large skillet over medium heat. Cook patties for 5 to 6 minutes per side until golden brown and fully cooked. In the final minute, top each patty with a slice of cheddar cheese and cover the skillet to melt the cheese.
04 - In a separate frying pan, cook bacon slices over medium heat until crisp. Transfer onto paper towels to drain excess fat.
05 - Remove bacon from pan, wipe clean, then add a small amount of oil or butter. Fry eggs sunny-side up or to preferred doneness. Season with salt and black pepper.
06 - Lightly toast brioche buns until golden and slightly crisp.
07 - Combine mayonnaise and hot sauce (if using) in a small bowl and spread evenly on the cut sides of each toasted bun.
08 - Layer each bottom bun with lettuce and tomato slices. Add a turkey patty topped with melted cheddar, then avocado slices, two bacon strips, and a fried egg. Finish by placing the top bun.
09 - Serve immediately while warm to enjoy the full range of textures and flavors.
