Make sure your chicken and veggies are chopped and ready to be cooked. Set aside.
Prepare the sauce by whisking together all of the 'sauce' ingredients in a small bowl. Set it aside.
In a large pan, heat 1 tbsp oil.
Cook your chicken breasts until almost all the way cooked, about 5 minutes, turning a few times.
Once mostly cooked, take the chicken out of the pan and set aside.
Add 1 more tbsp oil to the pan and throw the bell pepper and broccoli in.
After sauteing for 3-4 minutes, add in the garlic and ginger and cook for 1 more minute.
Stir in the sauce and let it thicken.
Once it starts to thicken, stir back in the chicken, and add the cashews and water chestnuts.
Cook for a few more minutes until thickened.
Serve over rice or cauliflower rice! Sprinkle with more cashews and sesame seeds.
