Place chicken in a bowl, and coat with the spice and vegetable mixture. Stir well to coat the chicken. Wash out the blender bowl with the 1/4 cup water and pour that over the chicken as well. Mix.
Pour the chicken and marinade into your Instant Pot. Cook on High Pressure for 5 minutes, and allow the pressure to release naturally for 10 minutes. Release remaining pressure.
Depending on your chicken and how much water it releases, you may need to remove the chicken pieces and evaporate some of the water by using the Sauté function to cook the sauce down.
