Assemble the spring rolls. Take a wrapper and place a heaping tablespoon of mashed potatoes at the center. Top with a heaping tablespoon of pulled pork and a generous amount of shredded cheese. Brush the sides of the wrapper with the beaten eggs and roll (see step-by-step guide on wrapping spring rolls
). Note that you don't have to keep the filling to a minimum. Every component of the filling is already cooked so there's no danger here of having raw meat in your spring rolls. Repeat until you have filled all the wrappers. Note too that you may have excess pork or mashed potatoes, or both.
