Pour the dressing into the salad bowl and mix well. Your salad is ready.
Remarks
If you don't have spring onions (scallions), you can use shallots instead or ordinary onions instead.
To keep to the spirit of the recipe, you really should try to use olive oil that comes from Crete; it's so good... If you can be tempted, allow me to recommend the one Arnaud sells, a real "must have".
