Flat Iron steak is my go to cut for a quick and inexpensive dinner. These steaks typically run about 5.99/lb at the grocery store so for around $12 you’ll have a steak that can feed 3-4 people easily. The flat iron is cut from the chuck area of the steer and has a similar texture to sirloin. It’s best cooked on the rare to mid-rare side, and as always, slice it across the grain for tender pieces.
