Creating Mashed Potato Egg Rolls is simple if you follow these easy steps:

1. Prepare the Filling: In a large bowl, combine the cooled mashed potatoes, shredded cheese, green onions, garlic powder, onion powder, salt, and pepper. Mix until well combined.
2. Set Up Your Workstation: Lay out the egg roll wrappers on a clean, flat surface. Keep a small bowl of water nearby to seal the egg rolls.
3. Fill the Wrappers: Place about 2 tablespoons of the mashed potato mixture in the center of each egg roll wrapper. Be careful not to overfill.
4. Roll the Egg Rolls: Fold the sides of the wrapper over the filling. Then, roll from the bottom to the top, sealing the edge with a dab of water.
5. Heat the Oil: In a deep frying pan or pot, heat oil over medium heat until it reaches 350°F (175°C).
6. Fry the Egg Rolls: Carefully place the egg rolls in the hot oil, frying them in batches to avoid overcrowding. Fry until golden brown, about 3-4 minutes per side.
7. Drain and Cool: Remove the egg rolls from the oil and place them on a paper towel-lined plate to absorb excess oil.
8. Serve Immediately: Enjoy your Mashed Potato Egg Rolls hot and crispy!
