Begin by placing some butter in your non-stick pan on a low-medium heat and allow it to melt
Whilst the pan gets to temperature, crack your eggs into a bowl and whisk gently until thoroughly combined and no white remains. Season.
Once the butter starts to gently foam and bubble, turn the heat down to the lowest it will go.
Add the eggs and start shaking the pan and stir the eggs around the pan with a spatula fairly vigorously
Keep doing this until a gentle scramble starts to form, cleaning down the sides of the pan as you go with the spatula
When the scramble is looking creamy and custardy, but still fluid enough to spread, use the spatula to spread into a smooth layer covering the pan
Allow to cook for a few minutes until the eggs look set but still moist
Tilt the pan and slowly roll up the omelette using the spatula
Gently invert the pan onto a plate to remove the omelette and brush with some melted butter. Garnish with chopped chives
