The first step, and arguably the most important one, in this recipe, is to season the steaks on both sides with salt and pepper.
           

Melt butter in a medium skillet over medium heat, then add the steaks and cook for 5 minutes on each side to get the perfect medium-rare steak.
          

To ensure your steak is nice and juicy, you must allow it to rest for 5 minutes before cutting into it.  
           

Slice the croissants in half like a hotdog roll and cook on a griddle for 30 seconds until lightly toasted
           

Add the slices of brie to each half of your toasted croissant and garnish with rocket leaves.
           

By this time, your steak should be ready to cut into ½ to 1cm thick slices. Add the steak to the sandwich and arrange the red pepper slices on top with the remaining rocket.
 

Enjoy your steak croissant sandwich!
