Sandwich Griller is a kitchen appliance that is used to grill and toast sandwiches. It typically consists of two hinged plates that press together to heat and toast the bread while melting the cheese and warming any filling inside the sandwich. They can be electric or stovetop and come in various sizes and shapes, including panini press and waffle iron-style grilled sandwich makers. Sandwich Griller is popular for making quick and easy grilled sandwiches, as they heat up quickly and do not require much time or effort to use.
