Step 1

Mash egg: Place the eggs in a bowl and crush with a fork. Once mostly broken up, use a potato masher to mash them up really well. Smaller egg white bits = creamier filling.

Step 2

Filling: Add remaining filling ingredients and gently stir to combine. Taste and add more salt if desired, but add with caution because it's bizarre how little salt eggs can take!

Step 3

Make sandwich: Butter the bread. Divide filling between 4 pieces of bread, spread evenly edge to edge. Trim crusts (optional), then cut as you wish. (Note 4 tips)

Step 4

Serve: Always serve at room temperature, for best flavour!
