myriad options in a tuna mayo sandwich. I quite like it with all the nonsense crunchy stuff, but probably overcomplicate it. Today my tuna mayo is
*Tuna (OBVIOUSLY)
*Mayonnaise (OBVIOUSLY)
* Sweetcorn
Red Onion
Red Pepper
*Paprika
Sriracha (only a little bit)

* = non-negotiable, everything else I can take or leave
