In a medium saucepan, sautée the minced garlic in avocado oil until lightly brown. Combine the coconut milk, nutritional yeast, sea salt, parsley, pepper, broth, and lemon juice.
Bring the sauce to a simmer and then add in the arrowroot flour. Let simmer for 10 minutes to thicken.
While your sauce is simmering, spiralize your zucchini. Place the zucchini in a large pan with a small amount of avocado oil and sautée for 5 minutes until soft.
Combine the sauce with the zucchini noodles and add in your diced baked chicken breast.
