Roughly chop the boiled eggs and place them in a bowl.
Add the avocado flesh, chopped chives, mustard, Greek yoghurt, lemon zest and juice.
Using a fork, mash everything together until you have a textured spread. Don't mash it completely smooth – a little texture makes it more interesting.
Season with salt and freshly ground black pepper to taste.
If time allows, leave the spread to rest for about 15 minutes before serving, allowing the flavours to develop.
Serve on crackers, toasted sourdough or your favourite bread, with a green salad on the side.
