What is a "sandwich plate"?

A sandwich plate is a flat, usually oval or rectangular dish specifically designed for serving sandwiches. It typically features a raised rim or edge to prevent toppings from spilling over the sides. Sandwich plates come in various materials, such as ceramic, glass, or melamine, and they may have decorative patterns or designs to complement the presentation of the sandwiches. Some sandwich plates also have sections or compartments to separate different types of sandwiches or to hold accompanying sides, such as chips or fruit.
