In a small frying pan over medium heat, toast the cashews for 3-4 minutes. Remove and allow to cool.
Cut the chicken according to the Note section. Into a small bowl, add chicken and 2 teaspoons of soy sauce. Add 1 ½ Tbsp pineapple juice if using breast meat. Mix and refrigerate for at least 15 minutes.
In a 1-cup liquid measuring cup, combine the sauce ingredients and whisk to combine. Set aside.
In a medium frying pan, over medium-high heat, add 2 tsp of oil. Place chicken slices evenly in the pan and let them cook in place for 2 minutes. Once browned, turn the chicken over to cook completely, about 2-3 minutes more. Remove and set aside.
To the same pan, add 1 tablespoon of water and the carrots. Cook for 1 minute.
Add 1 tablespoon of water and the peppers. Cook for 4 minutes.
Add 1 tsp oil and the onions. Cook for 2 minutes. Check vegetables for your desired doneness. Cook longer if needed.
Move the vegetables to the side of your pan and add the sauce mixture. Cook for about a minute and mix with the vegetables. Add chicken and juices back to the pan with the vegetables and toss to coat all.
Add the Green onion pieces and 1/4 cup of the toasted cashews. Cook for about a minute or until everything is warmed. Mix again.
Place 1/2 cup cooked rice on each plate. Divide the chicken/vegetables evenly over the rice. Add 2 tablespoons of cashews on top.
