Creating your delicious Bagel Breakfast Sandwich is straightforward if you follow these simple steps:

1. Prepare the Ingredients: Gather all your ingredients and tools. Slice the bagels in half if they are not pre-sliced.
2. Cook the Eggs: Heat a skillet over medium heat and add butter or cooking spray. Crack the eggs into the pan, season with salt and pepper, and cook to your desired doneness (sunny-side-up, scrambled, etc.).
3. Toast the Bagels: While the eggs are cooking, toast the bagels until golden brown. You can do this in a toaster or on a separate skillet.
4. Melt the Cheese: When the eggs are almost finished cooking, place a slice of cheddar cheese on top of each egg and cover with a lid to melt the cheese fully.
5. Assemble the Sandwich: Once the eggs and cheese are ready, place the cooked bacon on the bottom half of each toasted bagel. Add the egg and cheese, followed by avocado slices if using.
6. Top It Off: Sprinkle fresh chives or green onions over the eggs for added flavor, then place the top half of the bagel on each sandwich.
7. Serve Immediately: Enjoy your Bagel Breakfast Sandwich hot and fresh for the best experience.

By following these steps, you’ll have created an incredible breakfast treat in no time!
