The smaller sandwich you make with leftover ingredients after polishing off your main sandwich. An andwich typically contains fewer ingredients than the original sandwich, often a single slice of bread or torn half of a wrap, and is hastily thrown together. It's purpose is to use up extra ingredients, and fill whatever void the original sandwich failed to satisfy.
My sandwich was too small, but I had some extra turkey and avocado left on the cutting board, so I used them in a heel of bread to make an andwich.
