Start by preparing your tuna salad. Drain the cans of tuna and break any chunks apart in a bowl.
Cut the tomatoes in quarters or halves and add to the tuna. Cut the chives smaller and add the capers and spring onions a well.
Add the eggs
Add the mayonnaise and mix it all together. Season with salt and pepper to taste
Open the avocado’s at the last moment just before you are serving it.
Cut them open and remove the stone. Remove a bit of the flesh so there will be more space for the tuna salad. Any avocado you remove chop and add to the salad.
Pile the tuna salad into the boats and serve immediately
