To make the sauce, combine all of the sauce ingredients in a bowl and use a whisk to mix until smooth.
Reserve half the sauce for serving.
For the chicken
Marinate the chicken in the other half of the peanut sauce for at least 20 minutes.
Grill chicken over medium heat for about 5 minutes per side until cooked through (165 degrees in the center). Brush chicken with leftover marinade before flipping. Time will vary depending on how thick your chicken breast is. Let rest for 10 minutes and then slice. Keep warm.
While the meat is cooking, stir fry your veggies for about 5 minutes in 1-2 Tbsp olive oil. Keep warm.
Make the rice bowls
To serve, dish up 1/2 cup each of rice and veggies into each bowl. Add chicken and serve with reserved peanut sauce.
