For the rainbow sesame slaw: Combine the jicama, bell peppers, snow peas, rice wine vinegar, 1 tablespoon sesame oil, sesame seeds, soy sauce and 1 tablespoon sugar in a medium mixing bowl, tossing to combine. Set aside.
For the Sriracha lime mayo: Combine the mayonnaise, Sriracha, lime zest and juice in a small bowl. Set aside.
For the burger patties: Combine the chicken, scallions, soy sauce, 2 tablespoons sugar, 1 tablespoon sesame oil, lemongrass and garlic, gently mixing to incorporate. Divide the mixture into 6 patties and set aside. Heat a grill pan over medium-high heat, and brush with the vegetable oil. Place the patties on the grill and cook, turning once until done, 6 to 8 minutes per side. During the last few minutes of cooking, baste each burger with 1 tablespoon hoisin sauce.
To assemble, spread about 1 tablespoon of the Sriracha lime mayo on each bun bottom and top. Place the patties on the bun bottoms, top with about 1/3 cup of the slaw, add the bun top and enjoy! These burgers are great served with sweet potato fries or sweet potato chips.
