As a kid I thought that the best sandwich was "supper sandwich" an invention of my own.
Take two toppers or crusts from the end of a mothers pride white thick cut loaf. Toast lightly and spread with butter (margarine will not do) re-toast until the butter has melted, soaked in, and the bread has gone grispy and golden, then coat thinly with Bovril, add thin slices of hard cheddar cheese, grill until the cheese is melting, spread with peanut butter (crunchy) put the two slices together and eat with a mug of Cadburys hot chocolate.
As I am now older and supposedly wiser I forgo that for streaky bacon, with melted brie and (popped) poached egg breakfast baguette, two mugs of black coffee, (and absolutely nothing to do until my body has recovered from eating breakfast, this takes no more than 4 hours, which would be about lunch time and too late to start anything too taxing)
