Chop chicken into 1-inch, bite-size chunks and sprinkle with salt and pepper.
Make sauce by combining tamari, honey, garlic, ginger and chili paste in a small bowl.
Add bell pepper, carrots, snap peas, onion and chicken chunks into a large bowl. Toss with sauce.
Prepare a large rimmed baking sheet with cooking spray or oil and place veggie and chicken mixture on the sheet. Bake for 10 minutes, toss mixture and bake for another 10 minutes or until veggies are tender, but still crisp and chicken is cooked through. Remove mixture from baking sheet and serve over rice of choice.
