In a small bowl, combine soy sauce, honey, ketchup, rice vinegar, sesame oil, minced garlic, and red pepper flakes; set aside.
In a large rimmed skillet set over medium heat, cook ground chicken (or turkey). Break ground chicken up into little pieces using a spatula. Cook until no longer pink and all the liquid has cooked off; about 6-9 minutes.
Pour garlic sesame mixture into skillet. Toss the mixture together until chicken takes on the color of the sauce. The skillet should come to a simmer, cook until most of the liquid is thick and absorbed by the chicken.
To the skillet, add shredded cabbage, shredded carrots, and snow peas/sugar snaps. Toss together until coated well.
Serve and garnish with fried wontons, and green onions.
