Heat the avocado oil in a large skillet over medium-high heat. Add the chicken and cook, stirring occasionally, until it is no longer pink, about 7 minutes. While the chicken is cooking, spiralize the zucchinis and carrots. When the chicken is cooked, remove the pan from the heat and push the chicken to one side of the pan. Add all the sauce ingredients to the pan and stir them together. Put the pan back on the heat and stir the chicken through the sauce. Once the sauce thickens (about 1 min) add the veggie noodles to the pan and toss to coat them in the sauce. Let them cook for 3-4 minutes, or until they start to soften. Toss with the cashews and cilantro and serve right away.
