Forming pot stickers takes about 45 minutes, but then you have 4 days worth of freezer friendly dinner! Plus, these pot stickers only need 23 minutes to steam. Using pre-made wonton wrappers is convenient and you get restaurant quality results. Serve these as an appetizer or make a meal out of them. Serve with a 1:1 mixture of soy sauce and rice vinegar. Add Samba for a little heat.
Combine all filling ingredients in a large bowl-- pork, ginger, garlic, green onion, soy sauce, sesame oil, egg and cabbage. Stir until mixed together.
Set up a station to make the dumplings--2 sheet trays sprinkled with flour, a bowl of water, and gallon size freezer bags. Place 1 heaping teaspoon of pork filling onto each wonton wrapper. Moisten edges with water and fold over to form a triangle shape. Do not let filling get in the seam or it will open when it cooks. Press edges together firmly with fingers to seal. Set aside on flour surface until ready to cook.
Bring a large pot filled with 1" water to boil and add a steam tray. Place dumplings on top in a single layer and cover pot with lid. Steam over low heat for 23 minutes. Serve immediately with soy sauce, rice vinegar, and Sambal. Garnish with green onion.
Make Ahead Tip: You can easily freeze these dumplings and cook directly from frozen. To freeze, place sheet tray in freezer for 15 minutes. Remove the tray and transfer the pot stickers to a plastic freezer bag or a sealed container. Repeat to freeze as many as you want.
