Preheat the oven to 400°F (200°C).
Cut the bread into 3/4-inch (2cm) cubes (I'm not removing the crust, but you can).
In a large bowl, stir together olive oil, grated cheese, garlic powder, herbs, salt and pepper.
Add the cubed bread and toss until evenly coated.
Line a baking sheet with parchment paper (optional) and spread the bread on it. Make sure the bread cubes are spaced out a bit.
Bake for about 12-15 minutes or until golden on all sides.
Enjoy!
