Creamy Salmon Flan

Any fish can be used instead of the salmon, as could prawns or tofu. I used this filling in the lemony pie crust I wrote about in my last post.

Ingredients:
pie dough (see previous recipe)
200-300 g fish, prawns, or tofu
1 onion
oil
1 tbsp parsley (or basil)
1 handful chives, snipped into small pieces
1 cup cream (I used soy cream)
3 eggs
black pepper
1 tsp mustard
lemon juice
