Preheat oven to 350°F.
Rub the steak with Riley's All Purpose Seasoning on all sides and allow to rest at room temperature for 30 minutes.
Coat a cast iron or skillet with cooking spray. On high heat, sear the meat on each side until golden brown, about 1 minute per side.
Place in oven for 10-30 minutes, depending on the thickness of the steak. Once desired temperature is reached (see note below) let steak sit at least 10 minutes before slicing.
While the steak is sitting, spread asparagus on a baking sheet in a single layer. Spritz with cooking spray and sprinkle with salt and pepper. Roast for 10-15 minutes.
Slice steak and serve with hot asparagus.
