Combine the avocados, garlic, parmesan cheese, milk, salt to your tastes, oil and lemon juice in a food processor bowl. Process until smooth and creamy (about 2 minutes). Set aside.
Add reserved oil to a preheated nonstick pan or skillet on medium heat. Fry chicken until sauté until beginning to change colour. Add sun dried tomatoes and fry together with the chicken until chicken is browned. Add the zoodles; mix through chicken and tomatoes; and allow to cook through for 3-5 minutes, or until just beginning to soften (don't leave them too long or a lot of water will be released from the zucchini). Pour the avocado sauce over the top and stir through until warmed.
