Throw the peas and beans into a large
pan of rapidly boiling salted water. Bring
back to the boil for no more than 1-2 mins.
Drain and allow to cool naturally (rather
than plunging into iced water, which in
my opinion washes off flavour).
Dress while still warm in a little of the
olive oil, scatter over the spring onions
and season well. Finally, dress the lettuce
leaves in the remaining oil, the lemon
juice and zest. Season well. Toss together
with the peas, broad beans and spring
onions. Scatter the herbs over the top.
