Grilled Stuffed Flank Steak

"When it comes to steaks, I typically marinate my steaks for just a couple of hours (up to 12 hours) before grilling. I also like to toss a good steak rub on ’em before they hit the grill. For this Grilled Stuffed Flank Steak, I opted for a classic steak marinade of Worcestershire sauce and soy sauce with a bit of mustard and brown sugar. Delicious! I’ve used variations of this same marinade on a variety of different steak cuts, and it’s always worked out well. So stash this recipe away for whenever you need a good steak marinade! We typically use flank steak for fajitas, but this time I wanted to try stuffing that flank steak with some fun ingredients. I stopped by the store and picked up a flank steak, some frozen spinach and a jar of roasted red peppers. Back home, I pounded that flank steak out until it was pretty thin and then I spread the spinach and roasted red peppers on top. Roll, roll, roll. Skewer, skewer, skewer. Grill, grill, grill. Dinner done!"
