Preparation Steps

• In a bowl, mix flour and salt. Create a well in the center and add the egg and warm water. Stir until a dough forms.
• Knead the dough on a floured surface for about 5 minutes until smooth. Let it rest while preparing the filling.
• Combine mashed potatoes and cheddar in a bowl. Mix thoroughly and season with salt.
• Roll out the dough to about 1/8-inch thick. Cut into circles using a glass.
• Place a spoonful of filling in the center of each circle. Fold over and seal the edges by pressing with a fork.
• Boil a pot of water, then cook the pierogi in batches for about 5 minutes or until they float.
• In a skillet, melt butter and sauté the boiled pierogi until golden brown on both sides.
• Serve hot, garnished with green onions for a fresh touch.
