On a
lightly floured surface, roll out the pastry and use
to line a 23 cm/9 inch flan tin. Prick the base and
chill for a further 20 minutes.
Line the pastry case
with grease proof paper and fill with baking beans
or dried beans. Bake in a preheated oven, 200°C
(400°F), Gas Mark 6, for 10 minutes.
Lift out the
paper and beans and bake for a further 10 minutes or
until it is light golden brown.
Heat
the oil in a frying pan, add the onion and
courgettes and fry gently for 5-6 minutes until
lightly golden. Scatter over the base of the pastry
case and top with the sun-dried tomatoes.
Beat the ricotta, milk,
eggs,
herbs and salt and pepper together and spread over
the courgette mixture. Scatter over the olives and
bake for 30-35 minutes until firm and golden.
