Spiralize the zucchini into noodles and pat dry with paper towels to remove excess moisture.
In a large bowl, combine the zucchini noodles, shredded chicken, bell pepper, and purple cabbage.
In a medium bowl, whisk together the peanut butter, soy sauce, lime juice, honey, sesame oil, and minced garlic until smooth and creamy. Add 1-2 tablespoons of water if the dressing is too thick.
Pour the peanut dressing over the salad and toss until everything is well coated.
Garnish with fresh cilantro, chopped peanuts, and sliced green onions before serving immediately.
