One of the quickest meals in a hurry is steak, especially if you have a barbeque.
We usually use top sirloin, but occasionally we get a small prime rib roast and take steaks off of it:)
Steak is best if brought to room temperature before grilling on a hot grill (as hot as it goes). Season with salt and fresh pepper. Cooking time is determined by the thickness of the steak and the temperature of the grill.
