This is really good. I Used 3 Italian Pork sausages cut in 2 cm pieces. I also added a total of about 1/4cup of water while cooking. This recipe is a bit vague. Try these steps - preheat oven to 350 - Heat olive oil and then fry sausages until most pink is gone - add onions and continue for 2 mins - add green beans and continue 2 mins mins - add frozen perogies and 1/4 of the water - mix and stir all of it together - use a steel spatula so you can scrape and flip along the bottom to prevent the pierogies from falling apart - cook about 5 mins more turning, stirring  and adding the the rest of the water as needed to keep moist - effectively poaching the pierogies Add cracked pepper and sea salt  and stir - put into the oven for 10 mins -  turn at halfway - plate and serve with sour cream

It turned out amazing! I prepaired the sausage in a large iron skillet, used the same oil and added onion, minced garlic mushrooms, and frozen green beans. placed the veggies and sausage in a covered bowl while I sauteed the pierogies. Once the pierogies where done I combigned the meat and veggies into the skillet (covered) and placed it in the oven at 350 degrees for 15 minutes. Thanks for the recipe!
