A tender sirloin steak would also be a great choice for this quick and tasty dish. From Woman's World, April 24 2007.

I was looking for an easy flank steak recipe that didn't call for marinating, so I decided to try this one. Fantastic! Easy and so delicious. I didn't have whole grain mustard so I used dijon, otherwise followed the recipe. Cook time was spot on! Thanks for a great new recipe! I served this with baked potatoes and recipe#67534.
