In a medium bowl, combine the cabbage, sesame oil, rice vinegar, sugar, salt, and green onions. Toss well and refrigerate while preparing the burgers.
In a large mixing bowl, combine the ground chicken, teriyaki sauce, panko breadcrumbs, garlic powder, and salt. Mix gently until evenly combined.
Divide the mixture into four equal portions and shape into burger patties.
Heat avocado oil in a skillet over medium heat.
Cook the Chicken Teriyaki Burgers for 3–5 minutes on the first side until golden brown. Flip and cook another 2–3 minutes or until the internal temperature reaches 165°F (74°C).
Remove the burgers and lightly toast the brioche buns in the same skillet.
Spread your preferred sauce on both halves of each bun.
Add the burger patty, top generously with sesame slaw, and serve immediately.
