1Mix ground chicken, cilantro, soy sauce, garlic powder, lime juice, ground ginger, and ground black pepper together in a large bowl.
2Form the mixture into 4 patties.
3Prepare a skillet with cooking spray and place over medium heat.
4Cook burgers in the hot skillet until cooked through and no longer pink in the middle, 4 to 5 minutes per side. An instant-read thermometer inserted into the center should read 165 degrees F (74 degrees C).
5Serve on hamburger buns with slices of avocado and a 1 tablespoon ranch dressing.
