Add the sauce mixture and stir all the ingredients together until all the pork is cooked. Season with salt for taste and transfer to a large bowl to cool for 30 minutes.
Open package of egg roll wrappers. Remove 1 at a time to assemble egg rolls.
Begin with one of the corners of the egg roll near you. Place ¼ cup of filling horizontally across the center of the egg roll. Fold bottom corner over the filling, then fold the sides over the bottom corner. Brush top corner with the beaten egg wash and roll wrapper tightly closed. Place egg roll seam side down on a paper towel-lined baking sheet. Repeat the process until all the egg rolls are made.
Heat oil to 375 degrees. Gently lower the 3-4 egg rolls at a time into the oil for frying. Fry 3-4 minutes or until golden brown. Remove to a paper towel to drain, and keep warm in a 250 degree oven until ready to serve.
Serve with dipping sauce or hot mustard.
