Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
In a large bowl, combine the chicken, bell peppers, broccoli, and snap peas.
In a separate bowl, whisk together the soy sauce, honey, sesame oil, garlic, ginger, cornstarch, salt, and pepper. Pour this mixture over the chicken and vegetables, tossing to coat evenly.
Spread the chicken and vegetable mixture in a single layer on the prepared baking sheet.
Sprinkle the cashews over the top of the chicken and vegetables.
Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and the vegetables are tender. Stir halfway through cooking for even roasting.
Serve over cooked rice or quinoa, and enjoy!
