Cut the pork into 2" pieces. Combine the marinade ingredients in a bowl and add the pork, mixing to combine
Refrigerate for at LEAST 3 hours, but try to marinade overnight.
The next day, place the dried vermicelli noodles in a bowl and cover with boiling water. Let them soak for 5 minutes, or until they are softened.
Drain the noodles and set them aside.
Heat 2 tablespoons of oil in a wok or large cast iron skillet and add about ⅓ of your pork. The pork should be cooked in 3 batches to avoid over crowding the pan.
Stir fry for about 5-7 minutes, or until pork has a nice brown crust on the outside (by the time it gets a crust, it should be fully cooked).
Add the vermicelli noodles in the bottom of a bowl, then garnish with cucumbers, bean sprouts, pickled veggies, jalapenos and fresh herbs.
Place about ½ cup of pork on top and garnish with crushed peanuts. Pour ¼ cup of the Nuoc Cham over the whole dish.
