Take a bowl; add all-purpose flour, salt, garlic powder, black pepper powder, Italian seasoning, required water and make batter without any lumps and keep aside. It should be thick but runny, so it can coat easily.
Now take regular Mozzarella Sticks and cut into finger sized sticks or if you have string cheese sticks then cut into half.
Take a mozzarella cheese stick dip in the batter mixture and then coat in the bread crumb.
Again use the same process, dip in batter mixture and then coat in bread crumb and keep aside.
Use the same method (step 3 and 4) for remaining sticks and then all breaded sticks keep in fridge for 1-2 hours.
After 1-2 hours, heat the oil in deep pan; when the oil hot enough fry them till golden brown.
Remove the fried bread sticks on paper towel and transfer to the plate, sprinkle some Italian seasoning and serve with tomato sauce.
