Preheat oven to 350ºF.
Cut the thick bread slices into thirds so you have 3 sticks per slice of bread.
Combine remaining ingredients in a mixing bowl, beat well to combine.
Dip bread sticks into the egg mixture one at a time, and place on a baking sheet that has been sprayed with cooking spray.
Bake in a 350º oven for about 30 minutes. Flip the sticks over halfway through baking time to crisp both sides.
**To freeze, allow to cool completely before wrapping well in a freezer bag. To reheat, pop in a 350 oven for about 8 minutes to refresh. Alternatively, they can be reheated in a microwave for a minute or two, but they will lose their crispness.
