Bistro Beef Steak Sandwiches

  1. Preheat a grill or grill pan over medium-high heat. Slice buns and cook cut side down over direct heat until slightly charred and toasted.
  2. Coat the skirt steak in oil and season liberally with salt and pepper. Add the steaks to the grill over direct heat and cook for 2−3 minutes on each side for medium rare/medium (depending on the thickness). Remove steaks from grill, allowing them to rest for 4−5 minutes before slicing.
  3. Thinly slice the steaks on the bias and across the grain every ¼ inch or so. Pile the sliced steak high on the bottom side of the bun while generously coating the top side of the bun with the mayo and onions. Top off the sandwich and serve immediately.

Caramelized Onions

Basil-Balsamic Mayo
