Everything that comes with a Grand Slam put into a sandwich instead. They're very popular. You don't get a choice, you must be put down for one. Everyone gets Grand Slamwiches. They're very popular. Two eggs, a sausage, some bacon, some ham, mayonnaise, cheese, and maple spread all inside a sandwich.
