Whisk together the eggs, milk, vanilla extract, cinnamon, sugar, and salt. Set aside.
Heat a large skillet or griddle over medium-low heat.
Once hot, add cooking spray. Dip the sliced protein bread in the egg mixture and place in the skillet.
Cook for about 2 minutes or until golden brown before flipping and cooking an additional 2 minutes. For a larger batch, you can keep finished slices in an oven set to a low heat (~200ºF).
Serve with a dusting of powdered sugar, fresh banana slices, peanut butter, and syrup.
