Ultimate Grilled Cheese Sandwich

Cook the bacon and drain on a paper towel-lined plate. Allow to cool.

In a small skillet on medium heat, add unsalted butter. Once it melts, add an egg and season with salt and pepper. Cook egg for 2 minutes, and then flip over with a rubber spatula. Cook for another 45 seconds and then remove from the pan. Place egg on a plate and set aside.

Butter one side of each slice of bread with spreadable butter. Place a nonstick skillet on the stove and turn heat to medium. Place one slice of bread, buttered side down. Layer in the following order: most of the shredded cheddar cheese, bacon, and remaining cheddar cheese. Add the egg, sliced avocado, the slice of Muenster or Swiss cheese, and the second slice of bread with the buttered side up. Cook for 5 minutes. Using a spatula, gently flatten the sandwich. Flip over carefully and cook for another 3–4 minutes.

Slice the sandwich and serve immediately.
