In the context of sandwich makers, grillers are not much different except for slight variation in their plates. A griller has horizontal lines on its plates whereas a sandwich maker has diagonal lines that also cut the sandwich into two equal halves. Sandwich makers always seal the sandwich from the edges to ensure the filling does not squeeze out. If you already have an electric tandoor in your kitchen then you can also make a sandwich on it. You can make grilled toast grilled sandwiches and many more dishes that you can make on a grill.
