Place your flour in a bowl and lightly coat each string cheese piece with flour.
In another bowl mix together the egg and milk.
Mix together the panko crumbs, Italian seasoning, pepper and garlic salt in a shallow pan. I love using a pie tin.
Pour your canola oil into a deep skillet to the height of 1" up the side. Begin heating the oil on medium.
Take your flour dipped string cheese pieces and one at a time dip them into the egg/milk mixture then coat them in the seasoned panko crumbs.
After your oil has heated for a few minutes gently place one of the coated string cheese pieces into the oil. If the piece floats within 5-10 seconds the oil is hot enough. Cook 30-60 seconds on each side till it's nicely browned.
Let them drain/cool a minute on a paper towel-lined plate before enjoying with your favorite marinara sauce.
