Zucchini and ham quiche

Heat the oven to 180°C. To start, put all the water, oil, flour and salt in a bowl and mix everything together. Add more flour if it sticks too much. We make the dough thin and put it in an ovenproof bowl (I have greased the bowl with oil just in case). Put it in the oven for about 10 minutes and set aside.

Cut the onion and cook it with oil in a frying pan for 10 minutes. Cut the two zucchinis and after 10 minutes of onion, add the zucchini and cook everything together. 20 minutes more. The last five minutes add the ham. Let it all rest.

Beat the three eggs with the milk. Add salt and pepper. We join the previous preparation with this one and stir. Put it all in the dough. Optional put cheese on top. Bake in the oven for 40 minutes at 180°C.
