Make the filling: mix the pork, tofu, cabbage, scallions, garlic, ginger, soy sauce, sesame oil and pepper until sticky. Chill while you make the wrappers.
Melt the mozzarella and cream cheese in the microwave in 30-second bursts, stirring until smooth. Mix in the almond flour and egg and knead into a dough. Chill for 10 minutes.
Divide the dough into 16 balls. Roll each between two sheets of parchment into a thin 3 1/2-inch circle.
Place a heaping teaspoon of filling in the center of each wrapper. Fold into a half-moon and pinch the edges firmly to seal. Keep the finished dumplings on parchment.
Heat the avocado oil in a large nonstick skillet over medium heat. Add the dumplings flat side down and cook for 3 to 4 minutes, until golden on the bottom.
Carefully turn them, cover the pan and cook on medium-low for 6 to 8 minutes, until the filling is cooked through (160°F/71°C inside). Serve hot with the dipping sauce.
