Make the pastry: sift the flour into a bowl and rub in the butter until the mixture resembles soft bread crumbs. Then add the water and bring it all together using your hands to form a dough. Roll this out on a floured surface and press into a greased pie dish (this will only make enough pastry for a small dish so if you want to make a big tart double the quantities).
Cover the pastry with a piece of greaseproof paper and fill this with baking beans. bake at 180c for about 20 mins, or until the pastry has gone opaque and a bit crusty, but not brown. Then take away the paper and beans and bake for a further 5-10 mins. Don't let the edges brown too much. Remove from the oven.
While the crust is baking, half the red pepper and remove the seeds and the core. Place, skin side up, under a hot grill until the skin has charred all over. Allow to cool and peel the charred skin from the flesh. It should come away easily, but if you are having difficulty, put the hot peppers in a plastic bag and leave them to cool for 10 mins. This should help the skin to come away easier.
Slice the peppers into strips and arrange on the baked pastry shell. Fleck the shell with dollops of the cheese (be generous), and sprinkle over the chopped chives. Beat the eggs and cream, add a little salt and pepper to this and pour it in to the pastry shell. Bake this in your preheated oven at 200c for about 20 mins, or until it is puffy and golden.
