Cut cheese sticks in half and freeze until hard, about 30 minutes.
In a small bowl, combine the breadcrumbs, panko breadcrumbs, parsley, basil, oregano, and garlic powder.
In a separate bowl, add the flour.
In a third bowl, add the egg and whisk well.
Spray a large baking sheet with nonstick cooking spray.
Dip frozen cheese sticks into the flour, shaking off any excess flour.
Place sticks on prepared baking sheet.
When all of the sticks are coated, freeze on the sheet for at least 15 minutes, or until ready to bake.
When ready to bake, preheat oven to 400 degrees F.
Place the cheese sticks in the oven and bake for 4-5 minutes, turn sticks over and bake for an additional 4-5 minutes, or until sticks are golden brown and soft.
Serve warm with marinara sauce or ranch.
