The pies are very good both hot and cold, or heated in the microwave for 1 min.
Don't be scared if it doesn't come out perfect at first, even I failed on the first try - I used cold water to knead and the dough didn't want to spread. Follow the instructions and steps, and I assure you that it is worth the effort - after you get out of the first, then increase your work speed and skill.
Other fillings that you can make in this way - boiled potatoes in shell (puree), mixed with telemea and fried onions, pepper and salt: - minced chicken with onion, mixed with 2-3 eggs and 2-3 tablespoons of sour cream, salt and pepper. So these are the fillings I made and they came out perfectly.
