Combine pork mixture: In a large bowl, mix ground pork, minced garlic, grated ginger, green onion whites, soy sauce, sesame oil, white pepper, and salt. Mix with hands or fork for 2 minutes until well combined and slightly sticky.
Prepare tortillas: Divide pork mixture into 8 equal portions. Spread one portion evenly over one side of each tortilla, pressing thin and close to edges. Wet hands help prevent sticking.
Heat pan: Heat a large cast iron or nonstick skillet over medium-high heat. Add oil to lightly coat surface. Heat until oil is shimmering and hot.
Cook tacos: Place tortillas pork-side down in skillet. Immediately press down firmly with spatula or burger press. Hold for 30 seconds. Cook undisturbed for 3-4 minutes until pork is deeply browned and crispy.
Flip and finish: Flip tacos and cook 1-2 minutes on tortilla side until golden and toasted. Remove from pan and repeat with remaining tacos.
Serve: Top immediately with shredded cabbage mixture, green onion greens, cilantro, sesame seeds, and chili crisp. Serve hot.
