Creating delicious lumpia is simple when you follow these steps:

1. Prepare the Filling: In a large bowl, combine ground pork or chicken, grated carrots, chopped cabbage, chopped onions, and minced garlic.
2. Season the Mixture: Add soy sauce, oyster sauce (if using), salt, and pepper to the meat and vegetable mixture. Mix thoroughly until well combined.
3. Prepare the Wrappers: Take a lumpia wrapper and lay it on a clean surface, with one corner facing you.
4. Fill the Wrapper: Place a tablespoon or two of filling near the corner facing you. Be careful not to overfill, as this can cause the lumpia to break.
5. Roll the Wrapper: Fold the corner over the filling, then fold in the sides. Roll it away from you tightly until it forms a cylinder. Seal the edge with a bit of water or beaten egg.
6. Repeat: Continue filling and rolling the remaining wrappers until all the filling is used.
7. Heat the Oil: In a deep frying pan, heat enough oil over medium-high heat to submerge the lumpia.
8. Fry the Lumpia: Once the oil is hot, carefully place several lumpia in the oil, without crowding the pan. Fry until golden brown and crispy, about 3-4 minutes on each side.
9. Drain Excess Oil: Use a slotted spoon to remove the fried lumpia and drain them on paper towels to absorb any excess oil.
10. Serve: Let the lumpia cool slightly before serving, allowing the flavors to meld.
