Lay out a lumpia wrapper on a flat board. Have a small bowl of water nearby for sealing the wrapper. Place two rounded teaspoons of vegetable mixture on the lumpia wrapper. Center placement, but about 2" from bottom edge of wrapper.
30 Lumpia wrappers
Lift the bottom edge of the lumpia wrapper up and over the vegetable filling, rolling twice as you do so.
Dip your fingers in the water and dampen the left and right sides of the lumpia wrapper. Take the left side of the wrapper and pull toward the center, sealing the damp wrapper against the roll. Repeat with the right side of the wrapper.
Use fingers dipped in the water, dampen the remaining exposed upper portion of the wrapper. Now gently roll with just enough tightness to create a little tension. roll the wrapper up like a mini cigar. Use water to dampen any loose edges so they all lay smoothly.
Repeat until all 30 lumpia wrappers are filled. Let sit for a few minutes so all sealing water is absorbed.
While lumpia rolls are sitting, heat a few tablespoons of the remaining oil in a large skillet or electric skillet. Lay out lumpia in the hot oil, shallow frying and turning until golden brown on all sides, adding more of the remaining oil as needed. Work in small batches. Remove fried lumpia and lay on a paper towel to absorb any excess oil.
½ cup vegetable oil
