An alternative counter-top preparation method—one more common in the U.S.—employs a toaster oven where the sandwich (toastie) is arranged open face and then toasted (grilled), which not only toasts the bread but warms the meat and melts the cheese that is the traditional content of the classic Dutch toasted sandwich. While most informal eateries in Europe offer some form of toasted sandwich very few use clamshell-makers, preferring the grill or toaster-oven methods already mentioned, however American restaurants with a high customer turnover sometimes invest in large conveyor belt toaster ovens, such as can be found at Quizno's, Subway and Boston Market.
