Ingredients:

• Marinade for Ground Pork
• 1 1/2 Tbsp tapioca starch (can substitute cornstarch)
• 2 tablespoons soy sauce
• 1/4 pound ground pork
• 1 pound regular tofu (medium firmness)
• 1 leek or 3 green onions
• 1/4 tsp salt
• 1 tsp Chinese salted black beans (fermented black beans, also called Chinese black beans), or to taste

• 3 Tbsp stock (chicken broth)
• 1 Tbsp cornstarch
• 2 Tbsp water

Directions:

• Mix marinade ingredients.  Marinate pork for about 20 minutes.

• Chop leek or green onions into short lengths.
• Heat wok and add oil. When oil is ready, add the marinated pork. Stir-fry pork until the color darkens. Add salt and stir. Add the salted black beans. Mash the beans with a cooking ladle until they blend in well with the meat. Add the chili paste, then the stock, bean curd, and leek or green onions.
