Well I used a thick steak cut from the top region of a hind leg. I preheated my grill along with a small cast iron skillet. Cooked it for about 5 min. per side. Came out perfect. The skillet also help catch any ofthe cream cheese which oozed out. I will definately be making this again. I'm wondering if somehow if the cream cheese helps tenderize the meat as it melted in your mouth. Deffinately going to make this again. Next time I'll use a backstrap.
