What is "French toast"?

French toast is a popular breakfast dish that is made by soaking slices of bread in a mixture of eggs, milk, and vanilla extract, and then cooking the soaked bread on a griddle or frying pan until it is crispy and golden brown. The bread used for French toast is typically a thick, crusty bread such as brioche or challah, which is sliced and then dipped in the egg mixture. Once the bread is cooked, it is often served with toppings such as butter, powdered sugar, maple syrup, or fresh fruit. It can be customized with a variety of different flavors and toppings to suit individual tastes, and is a great way to use up leftover bread.
