Who doesn't have tuna in the cupboard and tomatoes in the fridge? This recipe does not need to be planned in advance, and if I do not have enough cream, I do half cream and half milk.
Depending on the furnace, it is not always necessary to cook the white pulp. We can then delete the first step of this recipe, and possibly place the pie in the oven low enough to be sure the dough is cooked enough. In this case, bake the quiche for 10 minutes more.
