Combine your egg whites, milk, cinnamon and vanilla in a bowl. Whisk until well blended.
Soak your bread in the mixture, one slice at a time, until it's partially saturated (Don't let it get too soggy or it will be a drag to get it out of the bowl) Make sure you soak on both sides of each slice.
To keep things lower in fat, cook in a non-stick pan without any oil. Keep the heat low to medium low so it doesn't burn. Cook a bit longer than you would regular french toast to be sure the egg gets cooked at the lower temperature.
Plate your food and top with your favorite French toast toppings!
