Steak sandwiches always hit the spot. In my take, tender, juicy strips of steak and caramelized onions are covered with melty havarti cheese and nestled in between two buttery slices of baguette. Yum!
Preheat an oiled skillet to high heat. Add beef to the skillet and season it generously with salt. Cook until the beef is just golden, remove from the skillet. Set aside.
