Creating the Egg and Cheese Croissant is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Croissants: Slice each croissant in half horizontally, creating a top and bottom section.
3. Whisk Eggs: In a bowl, whisk together the eggs, milk, salt, and pepper until well combined.
4. Cook the Eggs: In a skillet, melt the butter over medium heat. Pour in the egg mixture and cook gently, stirring occasionally, until the eggs are just set but still soft.
5. Add Cheese: Sprinkle the shredded cheese over the eggs in the skillet, allowing it to melt slightly.
6. Fill Croissants: Spoon the cheesy egg mixture into the bottom halves of the croissants. Place the tops back on.
7. Bake: Arrange the filled croissants on a baking sheet and place them in the preheated oven. Bake for 10-15 minutes or until the croissants are golden and crispy.
8. Serve: Remove from the oven and let cool slightly before serving. Garnish with fresh herbs if desired.
