Preheat the oven to 375 degrees F.
To cook the bacon using the "Mauro Method," line a baking sheet with parchment, overlapping each side 1 to 2 inches. Put the bacon on the parchment and bake until crisp and brown, about 20 minutes. This way, the fat will fry the bacon to a perfect crisp but not come in contact with the metal pan, creating a mess. Drain the bacon on paper towels and let cool. (Once the fat is cooled, use or just toss it. No mess!)
Crumble the bacon into a bowl. Gently mix in the eggs, mayonnaise, chives, mustard and lemon juice. Season with salt and pepper.
Eat alone, or build sandwiches with avocados and tomatoes on toasted croissants.
