Steak with mustard sauce

Description

The recipe won't take much time. Heat oil in a large shallow skillet over high heat. Season beef pieces with salt and pepper on both sides, then place them in the skillet. Cook, turning once, until browned, 2 to 3 minutes per side. Transfer the cooked steaks to a plate, loosely cover with foil, and let rest before slicing. Add vinegar to the skillet and cook until it thickens, 1 to 2 minutes. Remove from heat, add mustard, and whisk until smooth. Serve the meat hot with the mustard sauce.
