Beat the eggs with a small pinch of salt and pepper. Set out the bread, cheese, chicken, mayo, bacon, tomato, and Parmesan before heating the pan.
02 -
Heat a nonstick skillet over medium heat and add the butter. Pour in the beaten eggs and immediately place the two bread slices side by side on top of the wet eggs.
03 -
Cook for 2-3 minutes, until the eggs are mostly set and the edges look matte. Use a wide spatula to flip the egg and bread together so the bread side is against the pan.

On one slice, layer 1 slice cheese, chicken, mayonnaise, bacon, tomato, and the second slice of cheese. Fold the other bread slice over the filling to close the sandwich.
05 -
Sprinkle 1 tablespoon Parmesan over the top of the sandwich. Flip it Parmesan-side down and cook for 1-2 minutes until golden and crisp.

Sprinkle the remaining Parmesan over the top, flip again, and cook for 1-2 minutes more until the outside is crisp and the cheese inside is melted. Rest for 1 minute, then slice and serve warm.
