Lay a lumpia wrapper on a clean, flat surface. Spoon 25–30 g (about 1.5–2 tablespoons) of filling along the lower third, keeping a small margin at the edges.

Lightly moisten the edges of the wrapper with water. Fold the bottom over the filling, fold in the sides, and roll tightly towards the top edge. Seal the seam with a dab of water.

Heat 1.25 cm of vegetable oil in a skillet over medium-high heat until shimmering. Fry the lumpia in batches, turning once, until golden and crisp, about 4 minutes per side. Transfer to a plate lined with paper towels to drain excess oil.
