Generously salt and pepper both sides of each steak.
Add the steaks to the grill and cook for 2-3 minutes. Flip and cook for another 2-3 minutes. Add the goat cheese for the last minute of grill time, so that it melts slightly. (The times will depend on the size of your steaks and how well done you like them.) See my Ribeye Steaks post for more info about grilling steaks!
Remove from the grill and tent with foil. Let rest for about 3 minutes before serving.
Drizzle each steak with balsamic reduction and top with chopped parsley.
