Saute the chicken in the bacon grease in a large frying pan.
While the chicken is cooking, put all of the sauce ingredients in a blender or food processor and mix thoroughly until you get a smooth sauce. Add more water, if needed.
Remove the chicken from the pan and keep warm.
Saute the vegetables for the zoodles with the remaining bacon grease until al dente.
Add the chicken back into the pan. Turn the heat down to low.
Pour the sauce over the chicken. Warm the sauce gently, tossing to coat. Do not overheat.
Once warm, garnish with chopped green onion and/or chopped peanuts, if desired.
Serve immediately.
