This is the budget format of a pie that will perfectly fit into a family tea party, which is not a shame to treat guests and which you can easily experiment with by adding sausage, bacon, mushrooms or..., and about this little experiment that I had today - at the very end of the recipe.
Peel the onion and cut it into small pieces. Pour the vegetable oil into the pan and add the onion.
Fry on a low heat until Golden, stirring occasionally.
Grate the cheese. Beat the eggs. Mix the chilled fried onions, cheese and eggs. Add salt to taste. Stir.
Prepare the dough. To do this: pour the flour into a bowl and grate the butter. Add sour cream and mayonnaise with soda. Stir. Remove to the refrigerator for 25-30 minutes.
Distribute the dough in the form, forming the sides. Pour the filling on top. Bake at 180 degrees for 40-45 minutes.
Today I made a small experiment. I added spinach to the filling for the first time. And most importantly, the pie was made of puff pastry. It turned out very tasty! The puff pastry version is very suitable for quick preparation for unexpected guests.
