Roast the spaghetti squash using these instructions and set aside until ready to use

While the squash is roasting, prepare the rest of the recipe. Heat the avocado oil to medium-high and add the onion. Sauté, stirring occasionally, until onion is deeply brown, and almost caramelized, about 15 to 20 minutes. If at any point the onion begins to burn, reduce the heat to medium-low and add broth to deglaze the pan.

Add the garlic,  mushrooms, and chicken and continue cooking until the mushrooms have softened and the chicken has browned slightly, about 3 to 5 minutes. Add the chicken broth, thyme, sea salt, and lemon zest and bring to a full but gentle boil. Add the kale leaves and cover the skillet. Cook until kale has wilted and chicken is cooked through, about 3 to 5 minutes.

Once the spaghetti squash has finished roasting, remove it from the oven and allow it to cool enough to handle. Use a fork to release the spaghetti strands from the squash and place them in a large bowl.

Transfer the chicken mixture to the bowl with the squash and toss everything together until combined. Taste for flavor and add sea salt, and/or lemon juice to taste.
