Bacon, Egg, & Avocado Cheeseburger on a Pretzel Bun

1. Prepare Bacon: Cook bacon slices in a skillet over medium heat until crispy. Remove bacon, drain excess fat, and set aside.
2. Form Patties: Divide ground beef into four equal portions and form into patties about 1/2 inch thick. Season both sides generously with salt and pepper.
3. Cook Burgers: Heat the same skillet (or a grill) over medium-high heat. Cook patties for 3-4 minutes per side for medium-rare, or to desired doneness. During the last minute of cooking, place a slice of cheddar cheese on each patty to melt.
4. Cook Eggs: While burgers are cooking, heat a separate non-stick skillet over medium heat with a little butter or oil. Fry eggs sunny-side up, over easy, or to your preference. Season with salt and pepper.
5. Toast Buns: Lightly toast the pretzel buns if desired.
6. Assemble Burgers: Place a burger patty with melted cheese on the bottom half of each pretzel bun. Top with crispy bacon, a fried egg, and sliced avocado. Add any other desired toppings like lettuce, tomato, or onion. Place the top bun and serve immediately.
