Cut your 6 slices of bread in a half, diagonal shape. Set aside.
In a medium bowl, whisk together your eggs, milk, cinnamon, vanilla extract, sweetener of choice, and salt. Pour liquid into a shallow dish.
Heat up your large skillet and keep on low to medium heat. Add in a few tablespoons of vegetable oil once pan is hot.
Dip each slice of bread into your milk and egg mixture, coating both sides. Add soaked bread slices to the skillet once oil is hot. Cook 2 slices at a time (or more if you have a larger frying pan or a griddle). Cook for 2-3 minutes on each side or until desired texture and a golden brown color is achieved.
