Roll the dough between two floured sheets of greaseproof paper into a circle. Remove the top sheet of paper and press 7 cm cake tins with the edge in the dough, gently so that only a light print is visible. Use a knife to cut 1 cm around the edges of the molds. Turn around and press the dough into the bottom of the greased molds. Prick the bottom a few times ni with a fork, spread some of the filling over the bottom. Make circles in the filling with a fork. Bake the quiches for 20 minutes in an oven of 180ºC. Hot serve.
