Blend together the sauce ingredients, using the hot water to help melt the peanut butter.
Pour over chicken and mix well. Allow it to marinade for 30 mins if you have time.
Mix with remaining water, and cook at high pressure for 7 minutes, use natural pressure release for 10 minutes, and then release remaining pressure.
Mix with rinsed shirataki noodles and serve, garnishing with cilantro if desired.
*I used crunchy peanut butter so I'd save yet another step in chopping peanuts to serve on top. Yup. I'm just that lazy :) If you use smooth peanut butter, just scatter some roasted, chopped peanuts on the finished dish.
