Using a blender to make the Béarnaise sauce makes this recipe for open faced steak sandwiches a breeze. You can grill the steak for this sandwich using a grill pan on the stovetop OR on your outdoor grill, but do make a point of cooking the steak right before assembling the sandwich – he heat from the steak is really what makes this sandwich special. In fact, it elevates this sandwich from a lunch special to a dinner entrée all on its own.
Of course, if you’re someone who avoids carbs in their diet, you can skip the bread altogether and just make this a steak salad with Béarnaise sauce. It will be equally delicious.
