Turn temperature down to low and add the remaining ingredients (peanut butter, vinegar, water, miso, Cayenne pepper) and mix for 2 minutes.
At last add zoodles and mix everything gently together.
Let it simmer for another minute.
Garnish with parsley
Enjoy immediately!
Notes
Instead of water you can use vegetable broth
Instead of miso you can use soy sauce
Optional: Add 1 teaspoon sesame oil at the end
I use raw zoodles (spiralized zucchinis), but if you prefer you can cook your zoodles 2-3 minutes in salt water before you combine them with the peanut butter sauce.
