In a large mixing bowl, combine the diced apples, brown sugar, cinnamon, nutmeg, lemon juice, and cornstarch. Mix well until the apples are evenly coated.

Let the mixture sit for about 10 minutes to allow the flavors to meld.

Lay an egg roll wrapper on a clean surface with one corner facing you.

Place about 2 tablespoons of the apple filling in the center of the wrapper.

Fold the bottom corner over the filling, then fold in the sides and roll tightly to seal. Use a little water to help seal the edges.

Repeat with remaining wrappers and filling.

Heat the vegetable oil in a frying pan over medium heat.

Once the oil is hot, carefully add the egg rolls in batches, frying until golden brown on all sides, about 3-4 minutes.

Remove the egg rolls and drain on paper towels.

Serve warm, optionally with a scoop of vanilla ice cream.
