How to cook
Boil the pasta in salted water and drain it. Put it in a slightly greased tray. Heat oil in a pan on the stove and sauté the chopped onions. Once softened, gradually add the sour cream and mayonnaise that have been mixed together in advance to it.
Stir the sauce and season with salt and pepper to taste. Optionally, you can add other spices. Once the sauce comes to a boil, remove it from the heat and pour it over the pasta.
Slightly mix and put it to bake to a nice appetizing tan in a heated oven.
