Make the slaw: In a medium bowl whisk rice vinegar, sesame oil, coconut aminos, and sesame seeds. Toss with cabbage, bell pepper, and shallot. Set aside to marinate.
Make the mayo: In a small bowl, whisk mayo, sweet chili sauce, and sriracha until smooth. Chill until ready to serve.
Form the patties: In a large bowl combine ground chicken, chives, breadcrumbs, garlic, teriyaki sauce, salt, and pepper. Mix gently just until combined; form 4 patties.
Cook: Heat a lightly oiled skillet or grill pan over medium-high. Cook patties 5–6 minutes per side, until browned and the center reaches 165°F.
Assemble: Toast buns if desired. Spread 1 Tbsp sweet & spicy mayo on the bottom bun, add a patty, a mound of slaw, and drizzle a touch of teriyaki if you like. Top and serve.
