Separate the lumpia wrapper individually.
Lay flat one lumpia wrapper. Place one slice of plantain banana a 1 1/2 inch away from the edge. Add the jackfruit over the plantain and top it with brown sugar.
Grab the bottom edge of the wrapper close to the plantain and fold it over the fruits and roll twice. Fold in both sides of the wrapper and continue rolling until you reach almost the end. Wipe the edge of the wrapper and continue rolling to seal it. Do the same process with the remaining bananas.
In a large frying pan, heat oil over medium heat. Add the remaining sugar then mix. You can add as much sugar as you want.
Carefully place the rolls. Cook them 5 minutes on each side or until it's golden brown. Scoop those floating caramelized sugar over the rolls.
Remove from heat when both sides are golden brown. Drain on a cooling rack. Serve warm.
