Tart with leek and goat/sheep cheese

This is quite light tart, I tryed to make it as much healthy as possible. You can use any type of cheese, as long as it's soft and not too salty.

250 g whole wheat flour
1 t.s. salt
60 ml olive oil
120 ml cold water

700 g leek
2 tomatoes (or several dry)
200 g cheese
100 ml joghurt
3 eggs
2 tb.s. flour
salt, peper
butter

Make a dough, make it about 2-3 mm thin, put it in a springform, cut it with fork in several places and set in the fridge for 20 minutes.
Take it out, bake it in the oven for 10 minutes, 200C.
Leek and tomatoes (if fresh) place in a pan with little butter and simmer for 5-7 minutes, until excess water evaporates. Mix eggs, cheese, joghurt, salt, peper and flour and stir vegetables into this mixture.
Place in the oven for 30 minutes untill golden brown.
