Combine all the meatball ingredients & mix together well with hands.
Divide and form the meat mixture into 1 1/2 tablespoon sized balls.
Combine the sauce ingredients and set aside.
Heat a large skillet over medium high heat & add sesame oil once heated.
Add the meatballs to the pan and cook through on all sides - you can check the pork doneness with a meat thermometer, it should read 170 degrees ferenheit.
Remove meatballs and add celery, bell pepper, water chestnuts, peanuts (if using), & the whites of the green onion to the pan, add more oil if needed, and stir fry for a few minutes.
Add the meatballs back into the pan and pour in the sauce mixture.
Cook until sauce is thickened.
Serve over steamed rice, garnishing with the greens of the green onions & enjoy!
