What is the best way to cook a skirt steak, whether it's inside or outside on the grill?

The best way to cook a skirt steak is to season it with salt and pepper, then grill it over high heat for a few minutes on each side until it reaches your desired level of doneness. Rest the steak for a few minutes before slicing and serving. This method works well both indoors on a grill pan or outside on a traditional grill.
