Cook the Bacon: Place bacon strips in a cold skillet and cook over medium heat, turning occasionally, until crispy and golden brown. Transfer to a paper towel-lined plate to drain excess grease.

Toast the Bagels: While the bacon cooks, toast the bagel halves in a toaster or oven until golden brown. For extra flavor, you can toast them cut-side down in the skillet with the rendered bacon fat.

Cook the Eggs: In the same skillet over medium heat, crack the eggs. Cook to your preference (e.g., fried, scrambled, or folded). For a fried egg, cook for 2-3 minutes until the whites are set, then flip and cook for another 30-60 seconds.

Assemble: Place one slice of cheese on each bottom bagel half. Top with two slices of crispy bacon, followed by one cooked egg. Place the top half of the bagel on top to complete the sandwich.

Serve Immediately: Enjoy your breakfast bagel sandwich while it's hot and the cheese is perfectly melted.
