Making Delicious Cheeseburger Eggrolls can be achieved easily if you follow these steps:

1. Cook the Beef: In a skillet over medium heat, brown the ground beef with the chopped onion until fully cooked. Drain excess fat.
2. Season: Add salt, pepper, ketchup, and mustard to the beef mixture and stir well.
3. Incorporate Cheese and Pickles: Remove from heat and fold in the shredded cheese and chopped pickles. Ensure everything is well combined.
4. Prepare Eggroll Wrappers: Lay an eggroll wrapper on a flat surface with one corner pointing towards you.
5. Fill the Wrappers: Place about 2 tablespoons of the cheeseburger mixture near the center of the wrapper. Fold the bottom corner over the filling and roll tightly, folding in the sides as you roll to seal the eggroll.
6. Heat the Oil: In a deep skillet or fryer, heat your cooking oil over medium-high heat until hot.
7. Fry the Eggrolls: Gently place the eggrolls in the hot oil, frying in batches until golden brown and crispy, usually 2-3 minutes per side. Drain on paper towels.
