A toastie or toasted sandwich.
I think it's a toasted cheese sandwich - Breville is a brand of toasted sandwich maker
Un sandwich grille.
No, unless your idea of cooking involves injecting hydrogenated products into the sandwich.
Well my favorite toasted sandwich is this: Roast beef, pastrami, nubster cheese, lettuce, and mayonaisse on toasted Italian bread.
because toasted sandwiches have heat and that heat is hot enough to melt the chesse
Try a hot open faced turkey or roast beef sandwich, or a meatball with marinara sandwich, or any toasted sandwich from subway !
