Making the dough & crust:
-----------------------------------
To a mixing bowl combine the Flour ,salt and butter(cut in small cubes).

Using a pastry Blender or a fork, mix until the mixture resembles coarse crumbs.Add cold water in 1 tbsp at a time until the dough comes together being careful not to over mix.

Wrap the dough in plastic wrap and refrigerate for at least an hr.

After the dough has been rested for an hr. Lightly coat or spray a 9- inch fluted tart pan with  removable bottom.Roll the dough on a lightly floured surface and transfer to the pan to fit.Trim the edges and refrigerate for at least 10 mins before baking.

when its ready to bake, Preheat oven to 375 degree F .Line the Pastry with Parchment paper and fill with pie weights or Dried Beans.Bake until the crust is nice and set.Remove and cool on a wire rack.

Prepare the Filling:
------------------------
In a pan add a tbsp of oil or butter or combine both.Saute onions on medium flame stirring occasionally,

Sprinkle about a tsp of salt to sweat the onions,careful not letting the onions burn.As the onions cook down,you may need to scrape the pan every few  minutes until the onions turn golden brown. At the end of the cooking de-glaze the pan with little water or broth or wine.Remove after the liquid evaporates and the mixture is dry  to cool down.

This process  takes 30 minutes to an hr for the onions to completely caramelize.After its done,let it cool completely.

Meanwhile saute the sliced mushrooms in a tbsp of oil.let it cool.keep aside.

In a bowl,whisk 2 large eggs with milk and cream.Add the seasonings,salt and pepper.

Add the cooled  sauteed mushrooms,scallions and caramelized onions.Mix the shredded cheese.Pour the combined mixture on the prepared cooled Pastry Crust and bake for 30 minutes or until the custard is golden , puffed and the center is slightly wiggly and set.remove to a wire rack and let cool for 5 -10 minutes before slicing.Enjoy!!
