I decided to cook up a choice filet mignon. It was a little sucker but I only bought it to test. I did not use the GrillGrates because I currently have a minor fitment issue that I'm working with Yoder on.
I marinated it for about 30 minutes in some teriyaki sauce with fresh ground pepper, sea salt, worcester sauce and Cavender's Greek Seasoning. I smoked it at 200 degrees for about 30 minutes and then direct grilled to my desired medium doneness. Oh my goodness. Tender, moist and full of flavor.
I opened the door on the HMS and grilled on the expanded metal. You cannot expect good grill marks, but the flavor was there. One of the best fillets I've ever cooked and ever ate for that matter. I want another one! haha.
