Combine first 8 ingredients in a food processor until minced and mixed.
Slice pork into 1/4 inch thick or smaller slices. Freezing the pork slightly, before cutting, can make getting thinner slices easier.
Combine mixture and pork in a ziplock bag. Add lemon grass and Serrano pepper. Seal and marinate in refrigerator over night. Shake the bag a few times if you remember to help marinade coat pork well.
When ready to cook, cook the noodles according to package directions. Drain and rinse with cold water. Set aside.
Preheat grill to high heat. I use a grill tray on the flat side to keep the grill clean and let the meat cook in the juices.
Remove pork from marinade with careful focus to get rid of lemon grass.
Place meat on grill tray coated with cooking spray. Grill ~2-3 minutes each side until thoroughly cooked and slightly charred.
Prepare bowl with lettuce, mung beans, vermicelli in bottom and the rest of the topping and pork on the top and ENJOY!
