Cut cheese in half to make 24 pieces. Place cheese in freezer until frozen.
In small bowl, whisk the egg. Place flour on another small dish.
In separate bowl, combine bread crumbs, panko, parmesan cheese and dried parsley.
Dip frozen sticks in flour, shaking off excess, then into the egg and coat with crumbs.
Repeat with remaining cheese, placing them on a tray with wax paper. Place cheese back into freezer until ready to bake (this is a must or they will melt before the crumbs get golden).
When ready to bake, preheat oven to 400 degrees. Line a baking sheet with aluminum foil and lightly spray with oil.
Place frozen cheese sticks on baking sheet. Spray tops of mozzarella sticks with a little more oil and bake in bottom third of your oven until crisp, about 4 to 5 minutes.
Turn and bake an additional 4-5 minutes, watching them closely so they don't melt.
