Wash, dry, and finely chop napa cabbage (I like to stack them, cut the stem into 1/4 inch strips and then chop).
4 oz napa cabbage leaves
Add the chopped napa cabbage into a medium bowl, add salt and mix, set aside for 10 minutes.
4 oz napa cabbage leaves, 1/2 teaspoon salt
Place ground pork into a large mixing bowl and add chopped scallions, soy sauce, oyster sauce, sesame oil, garlic, sugar, and white pepper and mix.
1/2 pound ground pork, 1 scallion, 2 teaspoons soy sauce, 1 teaspoon oyster sauce, 1 teaspoon sesame oil, 1/2 teaspoon garlic powder or 1 clove minced garlic, 1/4 teaspoon sugar, 1/8 teaspoon white pepper
Add cornstarch to the pork mixture and mix.
1 teaspoon cornstarch
Grab small handfuls of napa cabbage and squeeze out the excess liquid, add the napa cabbage to the pork mixture, and mix evenly (discard the salty napa cabbage liquid).
