In a wok, heat a couple teaspoons of the oil and brown the ground pork.
Combine the five spice, teriyaki, oyster, and soy sauce, and pour over the pork.
Cook until the liquid has been absorbed.
Move to the side of the pan and add a couple teaspoons of oil to the bare side.
Add the package of the preserved mustard greens and saute for a couple minutes.
Combine the beef and suimiyacai.
Combine all the sauce ingredients in a small food processor.
At this point I added half the sauce directly into the meat and it was a bit too overwhelming. I plan on adding a portion of the sauce and about 3/4 cup water, stirring, and simmer until the liquid has been absorbed.
Serve with the lettuce wraps, and scallion and peanut garnishes.
