Skirt steaks, aged provolone, prosciutto and sage turn the tastebuds on in this unusually delicious dish. Easy, yet impressive and the assembly can be done hours in advance and stored in the fridge until ready to cook. I highly recommend getting a good, aged provolone. Boar's Head brand worked well for me. Courtesy Michael Chiarello's "Thinfully Delicious" episode of Easy Entertaining.
