Begin by cooking the eggs. Lower them carefully into boiling water and boil for 4-8 minutes depending on whether you like them soft or hard boiled.

Cool the eggs in ice-cold water for 1-2 minutes when they’re done; this will make it easier to remove the shell.

Place eggs, spinach, tuna and avocado on a plate. Serve with a hearty dollop of mayonnaise and perhaps a wedge of lemon. Season with salt and pepper.
