Whisk together eggs, milk, vanilla, cinnamon, and salt in a shallow bowl.
Dip each slice of bread into the mixture, letting it soak for a few seconds per side.
Heat a non-stick skillet over medium heat and add butter or oil.
Place soaked bread slices into the skillet and cook until golden brown on both sides, about 3-4 minutes per side.
Serve hot with maple syrup, a dusting of powdered sugar, or your favorite fruit.
