• Preheat the oven to 350 degrees F. and line a baking sheet with parchment paper.
• Tear the bread into 1" pieces and add them to the baking sheet. Bake for 5-7 minutes, stirring halfway through. Keep an eye on the bread during the last 2 minutes so it doesn't burn.
• Once the bread has cooled, add it to a food processor. Pulse until it is a breadcrumb consistency. Stir in the garlic powder, onion powder, Italian seasoning, and salt.
• Beat the eggs in a shallow bowl.
• Dip each chicken tender into the egg, then coat with seasoned breadcrumbs. Lightly spray both sides with olive oil spray.
• Air fry at 400 degrees F. for 10-12 minutes, flipping halfway through, until golden and the internal temperature reaches 165 degrees F.

For the oven:

• Preheat oven to 425 degrees F. and line a baking sheet with parchment paper. Set a wire rack on the baking sheet if you have one, this will help to crisp both sides.
• Place tenders in a single layer on the rack or baking sheet and lightly spray the tops with olive oil spray.
• Bake for 18-20 minutes, flipping halfway through, until golden and cooked through.
• For extra crispiness, broil the tenders for 1-2 minutes at the end - just keep a close eye on them.
