1In a large bowl, combine the ground pork, chopped cabbage, chopped green beans, shredded carrots, soy sauce, and black pepper. Mix well until all ingredients are evenly distributed.
Lay a lumpia wrapper on a flat surface. Place about 2 tablespoons of the pork and vegetable mixture near one corner of the wrapper.
Fold the corner over the filling, then fold in the sides and roll tightly. Moisten the other corner with a little water to seal the edge. Repeat with the remaining wrappers and filling.
Heat the vegetable oil in a deep frying pan over medium heat.
Fry the lumpia in batches, turning occasionally, until they are golden brown and crispy, about 3-5 minutes per batch.
Remove the lumpia from the oil and drain on paper towels.
Serve hot with your choice of dipping sauce.
