Lay your flank steak on a wooden board, pat dry. Place parchment paper over the top. Use a rolling pin or meat mallet and pound to 1/4 inch thickness. Season with salt and pepper. Set aside.
In a medium bowl, add the pork rind panko, garlic, pecorino cheese, parsley and basil and 2 tbsp olive oil, mix to combine. Sprinkle this mixture to cover the meat.
Add 4 slices of prosciutto, then provolone cheese, then last 4 slices prosciutto.
Starting on the short end, roll up like a jelly roll to seal. Tie with Butcher's twine about 1.5 inches apart. Preheat oven to 350 degrees F. Add 2 tablespoons olive oil to a 12 inch cast iron skillet. Heat to medium high heat. Add the braciole and brown on all sides. Pour in the wine and boil about 1 minute then stir in marinara sauce. Cover and bake for 30 minutes. Remove from the oven and baste with sauce. Bake another 30 minutes then remove cover and bake another 20-30 minutes until meat thermometer registers 165 degrees F.
Rest 15 minutes then slice and keep in the sauce. Serve immediately.
Store any leftovers in an airtight container in the fridge for up to 3 days.
