Pre-heat oven to 350 degrees and line a baking sheet with foil. Spray with cooking spray.
In a medium bowl, mix together all of the pork meatball ingredients until fully incorporated. Using a large spoon or a small cookie scoop, carefully roll pork mixture into small meatballs and place in a single layer on baking sheet. Bake for 20 minutes or until golden brown.
While the meatballs are cooking, prepare rice noodles according to package instructions. Place cooked noodles on a large plate along with the carrots, cucumber and herbs.
Working one lettuce cup at a time, fill each one with equal parts noodles, veggies, herbs and meatballs. Serve with dipping sauce on the side.
