3. Spray a cold large skillet with non-stick spray. In the skillet brown steak roll on all sides. Add vegetable juice cocktail and worchestershire sauce. Cover and simmer 55-60 minutes or until meat is tender, turning steak roll occasionally.
4. Meanwhile, in a medium saucepan heat the 1-1/2 cups water, onion, and bouillon granules to boiling. Add barley. Cover and simmer for 10-12 minutes or until water is absorbed. Remove from heat and stir in parsley.
5. Transfer roll to a cutting board. Stir together cornstarch and 2 Tbsp. water. Stir in liquid in skillet. Cook and stir until thickened and bubbly. Cook and stir 2 minutes more. To serve, remove skewers from meat and slice. Arrange slices on barley mixture. Spoon gravy on top.
