Preheat oven to 400 degrees.
Line a large sheet pan with non-stick foil and spray with non-stick cooking spray.
Place the diced chicken, vegetables, and cashews onto prepared baking sheet, spreading out evenly.
In a small bowl, whisk together the chili garlic sauce, soy sauce, vinegar, sesame oil, honey, and garlic. Pour the sauce over the chicken mixture and mix well with a spoon or tongs.
Bake in preheated oven for 15-20 minutes, until chicken is cooked through and vegetables are tender.
