• Preheat the oven to 350 degrees F. Line a baking sheet with parchment paper. Tear the slice of bread into 1" pieces and add them to the baking sheet. Bake the bread for 5-7 minutes, stirring halfway through.
• Once the bread has cooled, add it to a food processor. Pulse until it is a breadcrumb consistency.
• Pour the breadcrumbs into a bowl. Add the garlic powder and Italian seasoning and stir together.
• In a separate bowl, add the egg and whisk.
• Unwrap the string cheese and cut each one in half. Dip each cheese stick into the beaten egg, then coat with your seasoned breadcrumbs. Place the cheese sticks on a baking sheet lined with parchment paper.
• Put the baking sheet in the freezer for 1 hour. This will help prevent the cheese from melting out.

To air fry:

• Place the cheese sticks in the bottom of the air fryer basket. Spray them with cooking spray and cook at 390 degrees F. for 5 minutes. Flip the mozzarella sticks halfway through the cooking time and spray the other side with cooking spray.

To bake in the oven:

• Preheat the oven to 400 degrees F. Spray the cheese sticks with cooking spray and bake for 8-10 minutes.
• **Keep an eye on the cheese sticks during the last 2 minutes to make sure the cheese isn't oozing out.
