An open-faced sandwich is a type of sandwich that consists of a single slice of bread topped with various ingredients. Unlike traditional sandwiches, which have two slices of bread enclosing the filling, open-faced sandwiches showcase the toppings, making them visually appealing. Common toppings include meats, cheeses, vegetables, and spreads, allowing for a wide range of flavors and textures. These sandwiches are popular in many cultures and can be served as appetizers, snacks, or main dishes. Variations can be found in cuisines around the world, such as the Scandinavian smørrebrød or the French tartine, each featuring unique ingredients and presentation styles.
