Prepare the chicken dumpling filling:

• In a mixing bowl, combine the ground chicken, chopped cabbage, green onions, grated ginger, minced garlic, soy sauce, sesame oil, rice vinegar, black pepper, and salt. Mix well until all ingredients are thoroughly incorporated.

Form the burger patties:

• Divide the chicken mixture into 4 equal portions and shape each portion into a round patty, roughly the size of your burger buns. You may need to press the edges slightly to ensure the patty holds its shape.

Cook the patties:

• Heat a skillet or grill pan over medium-high heat and lightly grease it with a little oil or non-stick spray.

• Cook the patties for about 5-7 minutes on each side, or until the internal temperature reaches 165°F (74°C) and the patties are golden brown and cooked through.

Toast the buns:

• While the patties cook, melt the butter in a separate pan over medium heat.

• Cut the burger buns in half and toast them in the pan for 1-2 minutes until golden brown. Set aside.

Assemble the burgers:

• Place a lettuce leaf on the bottom half of each toasted bun (optional), then add a chicken dumpling patty.

• Top with sliced tomato (optional) and the top half of the bun.

Make the dipping sauce (optional):

• In a small bowl, whisk together soy sauce, rice vinegar, sesame oil, honey (if using), and chili flakes (if desired).

Serve:

• Serve the Chicken Dumpling Burgers immediately, with the dipping sauce on the side for added flavor.
