Method

Blanch the beans in boiling water for 3-4 mins until al dente, adding the spring onions for the final 2 mins. Plunge the vegetables into ice-cold water, then drain and set aside.

When ready to serve, heat the oil in a frying pan, tip in the veg and warm through. Add the olives, heat a little longer, then remove from the heat and stir through the lemon juice, tarragon and some seasoning.
