Pay particular attention to the visual aspect of your sandwiches: a visually unappealing sandwich will not sell.

Ideally, a sandwich's filling should have three colours, making it both appetising and easy to understand what is in it. 

Examples with simple recipes: 

  • Ham - cheese - lettuce:
    pink/yellow/green

  • Tomato - mozzarella - marinated bell pepper
    red/white/green
