01 - Whisk together flour, eggs, water, salt, baking powder and 1 tablespoon oil until smooth. Let rest for 10 minutes to allow proper hydration.
02 - Heat non-stick skillet over medium heat with oil. Add ground pork or chicken, ginger and soy sauce. Cook breaking up meat until no longer pink, about 3-4 minutes.
03 - Add grated carrot and napa cabbage to skillet. Stir-fry 2-3 minutes until vegetables soften. Mix in sesame oil, scallions and black pepper. Remove from heat and set aside.
04 - Wipe pan clean and return to medium heat with light oil coating. Pour one quarter of batter, swirling to coat bottom into thin 7-8 inch pancake.
05 - When bubbles form and edges set, about 2 minutes, spread one quarter of filling and drizzle beaten egg on half the pancake. Fold over covering filling, press gently and cook 2 minutes per side until golden.
06 - Continue with remaining batter and filling to create 4 stuffed pancakes total.
07 - Combine soy sauce, rice vinegar, sesame oil and chili flakes in small bowl. Mix well until incorporated.
08 - Slice pancakes into halves or quarters and serve hot with dipping sauce on the side.
