Preheat oven in a heavy pot to 350. Start making the rolls as the oil heats, keeping an eye on it so it doesn't get too hot.
Whisk the egg in a small bowl with a splash of water.
Lay one of the wrappers out on the work surface. Brush two sides and a corner with the egg wash.
Add a slice of cheese so it is a square of cheese within the square wrapper. Add the ham on top, cutting off any extra ham so that the ham is pretty much the same size and shape as the cheese.
Place down 3 pickle chips in a line, so that the line is dividing the wrapper between the egg washed corner and the dry corner. Top with some pork and a small scoop of the mac and cheese.
Roll the wrapper around the filling starting with the dry side. Roll it over half way, then fold in the sides and roll it the rest of the way. Make sure it is sealed on all edges. Continue to make the rest of the egg rolls.
Fry in batches of 2 -4 depending on how big the pot is. Fry until uniformly brown and crispy, and remove them from the oil if you see any of the cheese leaking out.
Transfer to a wire rack to cool, then serve with the honey mustard.
