I can remember learning about how the name sandwich came about, when I was at school. It was the Earl of Sandwich, that wanted to eat, and a sandwich was created for him.
Sandwiches are supposed to be food, between 2 slices of bread, but I tend to be more creative, and make them on thin bagels, or croissants. Right now I am eating a croissant, with rotisserie chicken, thickly carved by me, and English Branston Pickle. Just amazing.
Managed to take a photo, before it had all gone.
