Trim the ends of leeks, discarding any thick, dark green leaves. Rinse well under running water as leeks often have mud hidden between their leaves.
Slice into rounds and rinse again in a colander if you can see any mud.
Heat 2 tablespoons of olive oil in a non-stick frying pan over a medium heat.
Add the leeks and stir well, cooking for around 10 minutes until softened. You can cover with a lid and reduce the heat to low to speed the process up a bit. Stir often.
Season with salt if desired.
