Prep. Chop the leftover pulled pork to a fine consistency, similar to ground.
Roast the peppers over an open flame or under the broiler until charred all over. Steam them for about 15 minutes by placing them in a closed container. Once softened, remove the outer skin from each one, remove the cores and seeds, then dice fine.
Chop off the stalky end of the leek, cut in quarters lengthwise and soak in water to remove any dirt between layers. Once rinsed, dice fine and add to the peppers.
Julienne the carrots and cabbage and add to the mix. Add the chili sauce, and toss to combine, making sure everything has an even coating.
Cook. Heat the oil in a medium saucepan over medium-low heat. Add the stuffing mixture, stir, and sweat the mixture for about 8 to 10 minutes, avoiding overcooking. Allow to cool in the pan.
Roll. Create a working area on your counter with your stuffing mixture, your wrappers and a small bowl of water. Place an individual wrapper on a small plate with one of the pointed ends oriented toward you. Take about 1-1/2 tablespoons of the mixture and place it at the lower third of the pointed end closest to you.
Lift the pointed corner of the wrapper closet to you pulling it up and over the top of the mixture. Next, fold each east-west corner over the top of the section you just rolled. Use a little water on your finger to glue down the edges. Finally, roll the log you have created toward the pointed end furthest from you. Moisten the final flap with a little water, the wrapper should seal itself. If it doesn’t, use a little more water to do so. You should have enough mixture to yield about 20 egg rolls.
Fry. In a deep pan or a fryer, add the frying oil so it’s a couple inches deep. Preheat to 350°F (176.7°C). Fry 2-3 egg rolls at a time for about 4-5 minutes or until golden brown. If frying in a pan, turn them over until each side has browned. Drain each roll on some paper towels and allow to cool a bit.
Serve. Serve warm with the Asian BBQ sauce for dipping.
