Finely cut the lemongrass, shallots, and garlic. Then, blend them together with water using a food processor. Put on the food prep gloves and squeeze the lemongrass mixture over a sieve to extract the juice. Slice the pork belly into bite-sized strips (avoid cutting it too thin). Season the meat with half of the lemongrass juice, pepper, salt, soup powder, five-spice powder, honey, condensed milk, and caramel sauce. Mix well and marinate for at least 15 minutes. Season the ground pork with the remaining lemongrass juice and the exact same spices. Mix well and let it rest for at least 15 minutes.
Cut the carrot, kohlrabi, and green papaya into pieces, then slice them finely. Season them with sugar and salt. Marinate for 15 minutes to improve their crispness.
Combine vinegar with sugar. Bring the mixture to a boil, then let it cool.
After the ingredients have been well-marinated, preheat your oven to 400°F. Brush or spray a little cooking on the grilling tray to prevent the pork from sticking to it.
Shape the marinated ground pork into flat, round meatballs. Press the pork using your palm to get it into the perfect shape. Repeat until you run out of ground meat. Once done, place the meatballs onto the grilling tray. Spray some oil on the meatballs. Grill the meatballs for 12 minutes at 400°F.
While waiting for the meatballs to cook, thread the pork pieces into the skewers.
Once you've finished cooking the meatballs, move on to grilling the pork.
Spray a little oil on the pork's surface to prevent them from drying out. Then, grill them for 12 minutes at 400°F.Once done grilling, transfer the pork and meatballs to a clean pot and cover it with a lid or aluminum foil. Combine warm water with fish sauce and sugar. Stir well, then add garlic, chili pepper, and juice of 1 or ½ a lime. Do a taste test and adjust the spices to your liking.
Put on a pair of food prep gloves. Squeeze the pickled vegetables to remove the excess liquid. Then, pour the vinegar and sugar dressing over the veggies.
Place the pork skewers and meatballs on a plate next to the vermicelli noodles, pickled vegetables, and herbs.When serving, spoon the dipping sauce into a bowl together with the pork, meatballs, and pickles.Enjoy them with the noodles and herbs on the side.
