Sammy and the skyscraper sandwich

Sammy was very hungry.
'I'm so hungry I could eat the biggest sandwich in the world,' he said.

Sammy is raiding his mother's cupboard to make himself the biggest sandwich in the world. But will the sandwich with the chocolate spread, mustard, chocolate vermicelli, raisins, jam, peanut butter, a spoon of sweet honey and almost everything in the fridge be enough to appease his hunger? You've never seen a skyscraper sandwich, have you?
