Mix the dipping sauce and set aside. Combine the chicken and its marinade ingredients and marinate for 30 minutes or longer as desired.
Cook the rice noodles according the the package and rinse under cold water until cool, then use kitchen scissors to cut into smaller pieces and toss with sesame oil.
Heat a tbsp of oil in a skillet over medium high and add the chicken. Cook, stirring, until browned and cooked through. Since this marinade has sugar, it can start to burn, so add a bit of water as needed to keep the pan from getting too dry. Mix the chicken in with the rice noodles and add the scallions and toss it well.
Set up a baking sheet lined with parchment and sprayed well with oil spray to set your rolls on. Once the rice paper is wet it is very sticky, which is great for keeping the roll together, but it sticks to everything else also. Also grease a plate or cutting board to use for forming the rolls. Fill a large bowl big enough to hold the rice paper rounds with warm water.
Place one round into the warm water for about 30 seconds to soften. Spread it out on the greased plate and fill with about 1/4-1/2 cup of the filling. Roll it up like you would a burrito or spring roll, making an envelope and then rolling into a log. Seal the edge and place seam side down on the greased baking sheet. The roll will seal itself together while it waits to be fried.
Once you have formed all your rolls, heat a skillet over medium high with about 1/4 inch of oil in the bottom. When it is hot, add the rolls, making sure they don't touch each other because they will stick. Fry on one side until crispy and starting to brown, then flip them. Serve on a lightly oiled platter so they won't get stuck to that also. :) Serve with plenty of dipping sauce.
