Cook the Bacon: In a skillet over medium heat, cook the bacon until crispy, about 4-5 minutes per side. Transfer to a paper towel-lined plate to drain.

Prepare the Mayo Spread: In a small bowl, mix the mayonnaise with Dijon mustard (if using) for extra flavor. Spread this mixture evenly on one side of each slice of toasted bread.

Baked Goods

Assemble the Sandwich: Layer the ingredients on two of the slices of bread: start with the lettuce leaves, then layer the sliced tomatoes, and season with a pinch of salt and black pepper. Add the crispy bacon strips on top, followed by avocado slices or a fried egg, if desired.

Top and Serve: Place the remaining slices of bread on top to complete the sandwiches. Slice in half, secure with toothpicks if needed, and serve immediately.
