A super lazy pie (from Masha)

The original recipe comes from a friend of mine, an accomplished cook of Russian fast'n quick recipes. She makes this with sauteed cabbage but the dough is so flexible that it goes well with any type of filling. Over the years, I've come across quite a few versions of the pie and I've included them below. Buyer beware, I haven't tested those.

• 3/4 cup sour cream
• 3/4 cup mayonnaise
• 3 large, or 4 med egg
• 3/4 cups flour
• 1 tablespoons baking powder 

Preparation:

1. Mix the ingredients till dough has consistency of thick sour cream. Pour half of the dough into a baking pan, spread the filling, pour the other half on top of the filling. 
2. Bake in a 350F preheated oven for 30-40 minutes.
   
   The filling of the pie can be anything you'd like: sauteed vegetables, potatoes + meat, potatoes+sauteed mushrooms, any variations of meat, apples, etc.
