Imagine everything good about a cheesesteak but amped up to the umpteenth degree. Now stop dreaming, because this colossal focaccia cheesesteak is just that, featuring tangy-hot Calabrian chili aioli, piled high with thin slices of steak and melted American cheese, crowned with caramelized peppers and onions. This slab of a sandwich houses everything good under one bready roof. Set it out and let guests slice it into whatever sized portions they want with ease. And while it might not be a traditional Philly cheesesteak in any sense of the word, it hits all the marks of a delicious and crowd-pleasing game-day treat nonetheless.
Thinly sliced steak can be found in the fresh or frozen section of well-stocked grocery stores. If unavailable, ask your butcher to thinly slice it for you. And if all else fails, throw a boneless rib eye or skirt steak in the freezer until firm and use a sharp knife to slice it yourself. Freezing the meat makes it easier to slice and prevents it from sliding around, so freeze for at least 30 to 60 minutes before slicing.
