My mum used to make this when i was younger. It is great to take to work as lunch. Prep time is a guess.

For the base: sift flour into a bowl , rub in butter , add egg yolk and enough water to mix to a stiff dough.

Refridgerate 30 minutes.

Roll pastry to fit base of a rectangle tin.

For the filling: spread well drained tuna over the pastry.

Saute chopped onion& chopped celery in 15g butter , until onion is transparent.

Spread over tuna.

Melt remaining butter , add flour and 2 tsps of curry powder , stir until smooth.

Add milk gradually , stir until sauce boils& thickens , reduce heat , add 30g grated cheese , stir until melted.

Add salt& pepper.

Add lightly beaten eggs , mix well.

Spread the cheese sauce evenly over the onion& celery.

Combine remaining grated cheese , remaining curry powder and paprika , sprinkle on top of slice.

Bake in a moderate- hot oven for 10 minutes , reduce heat to moderate , bake further 25- 30 minutes or until golden.
