Place a bit of flour on a clean surface and flip the flank steak a few times to coat both sides. A meat pounder will help you flatten the steak until it is less than 1/4 inch thick and approximately a foot square.
A shallow dish should be used to place the egg and water.
Combine the bread crumbs, grated parmesan cheese, salt, and pepper in another shallow dish.
Cooking oil should be heated to 360 degrees Fahrenheit in a deep skillet.
Make sure the flattened steak is fully coated in egg mixture, then dredge it in the seasoned bread crumbs and cheese mixture.
The steak should be slid into the hot oil and cooked for about 4 minutes until it turns a light brown color.
Place the cooked steak on paper towels and roll it up as soon as possible so that it fits inside the bread.
On top of the shredded mozzarella cheese, place the rolled steak inside the sliced Italian bread.
Add giardiniera to your taste and warm marinara sauce over the steak.
If the sandwich looks different from what you're used to, that's how a breaded steak sandwich should look.
