One-Pan Croque Monsieur Breakfast Sandwich

Whisk together eggs, salt, pepper, and nutmeg in a small bowl until combined.

Melt butter in a large nonstick skillet over medium heat. Add egg mixture, tilting skillet to coat bottom of pan. Quickly dip one side of bread slices into egg mixture, then turn over slices to coat with remaining egg mixture in skillet. Cook bread slices for 1 to 2 minutes or until egg is set. Using a wide spatula, turn over both egg and bread slices together.

Top one slice of bread with ham, Gruyère, mozzarella, and 1 tablespoon Parmesan cheeses. Cook 1 to 2 minutes or until golden. Top with microgreens. Turn remaining bread slice over and on top of sandwich; fold in any cooked egg pieces. Transfer to a plate; cut sandwich in half. Garnish with additional Parmesan cheese, if desired.
