Slice the croissant lengthways. Try to keep the croissant attached slightly so that you can open it up like a book. Layer your cheese and ham on the bottom half of the croissant.
Add the butter to a small saucepan and put on a medium heat. Crack in the eggs, add salt and pepper, then stir with a wooden spoon. As they cook, continue to break up the eggs until they are beautifully scrambled. Cook to your liking.
When the eggs are done, spoon them on top of the ham. Put the top half of the croissant back on top, then put it all on a baking tray. Pop in the oven for 5 minutes or until warmed through with melty cheese. Enjoy!
