An alternative way to use onions-Swiss onion pie 

Today I propose a Swiss recipe, a savory onion pie that I have often tasted on holiday in Zurich ...
The base of the cake has a fairly crumbly dough, which counts against the softness of the filling. For all those who are not onion lovers, I propose as an alternative the use of zucchini or another vegetable of your choice (adding later however the composed of milk and eggs) .I hope to be able to make the sweet version of this cake soon, that is the one with fruit ... For now I propose the recipe in the video and I assure you that it is tasty.
Ingredients for the dough:
150 g. made with flour
a teaspoon of salt
3 or 4 tablespoons of cold water
Ingredients for the filling:
750 g. of onions
a pinch of salt and pepper
a spoonful of extra virgin olive oil
2 spoons of flour
200 ml of milk
a whole egg
