2 - 16 oz. packages store-bought potato and onion pierogi
1 T. olive oil
10 oz. fresh spinach
1 small onion, diced
2 cans condensed cream of mushroom soup

Preheat oven to 350 degrees. Spray an 8 x 8 inch casserole dish with non-stick cooking spray.
Boil pierogi according to the package directions, about 4-5 minutes or until they float to the top; drain.
In the meantime, in a large skillet/pan, heat olive oil over medium-high heat; add onion, spinach, salt and pepper; sauté until onion is cooked through and spinach is wilted.
Spread a good dollop of the cream of mushroom soup on the bottom; add half of the pierogi; add half of the cooked spinach and onions; top with the cream of mushroom soup. Add a layer of Mozzarella cheese and a sprinkle of Parmesan cheese. Repeat these layers with the remaining ingredients in order: pierogi, spinach, soup, Mozzarella cheese and Parmesan cheese.
