I cooked up some fajitas last night and they were awesome! I marinated in Worcestershire, oil & garlic. I looked at some recipies and it called for cooking the skit steak for 5 - 7 minutes per side on a hot grill. That sounded excessive as I had the egg dialed in at 600 dome and likely much hotter at the grid level.
Instead I cooked for 2 minutes per side and let it rest 5 minutes. It was some of the best steak that we have had and was VERY tender after being slice cross grain against the basis.
