Preheat oven to 375, and cook bacon in a pan; drain and chop. Cut off the tops of each croissant, pulling upward to remove the tops.
In a bowl, scramble your eggs. Stir in cheese and vegetables. Place croissants on a parchment paper lined baking sheet and spoon in egg filling. Top with bacon and more cheese if desired.
Place in the oven and bake for 25 minutes until egg is no longer runny. Enjoy!
