Prepare the Spring Rolls
One at a time, dip rice papers into warm water for 5 seconds. Remove and place on a clean towel or cutting board. Place all ingredients save the two sauces in the center (horizontally), wrap and tuck the sides, then the bottom flap, and then carefully tuck and roll until closed. Cover with plastic wrap until serving.
Plate the Dish
Place spring rolls on a cutting board and cut them in half on a bias. Place the sliced spring rolls on a plate either standing up or lying next to each other. Fill two small dishes with the dipping sauces and place onto plate.
