Spiralize the zucchini using your spiralizer.
Heat the avocado oil over medium-high heat in a large skillet.
Once the skillet is hot, add the strips of chicken breast and arrange them evenly. Sprinkle with sea salt and pepper. Allow to brown undisturbed for 3 minutes.
Stir the chicken, cooking for another 3 to 5 minutes until golden brown.
Stir in garlic, coconut milk, sun-dried tomatoes, and olives; bring to a full boil.
Incorporate gluten-free flour, stirring until clumps disappear. Boil for about 4 minutes until thickened.
Add zucchini noodles to the skillet, stirring them into the sauce. Cover and cook for 3 to 5 minutes until tender.
Taste the sauce and adjust seasoning. Optionally add lemon juice or parmesan cheese before serving.
Serve warm and enjoy!
