In a skillet over medium heat, cook the bacon until crispy, about 5-7 minutes. Remove and drain on paper towels.

In the same skillet, crack the eggs and cook to your desired doneness, seasoning with salt and pepper.

On each slice of toasted bread or bagel, place a slice of cheese, followed by two slices of bacon, and top with the cooked egg.

Add another slice of cheese on top and cover with the other slice of bread or bagel.

Return the assembled sandwiches to the skillet and cook for an additional 2-3 minutes on each side until the cheese is melted.
