Preheat oven to 400 F.

Cut the spaghetti squash in half lengthwise. Place the squash cut-side down on a baking sheet and bake for 30-35 minutes, or until the skin gives when you press your finger to it. Remove the squash from the oven and reduce the oven temperature to 350 F.

Grease a dutch oven or an 8-inch square glass baking dish with 2 Tbsp of the butter (or ghee/coconut oil).

Let the squash cool for 5 minutes, remove the seeds, and then use a fork to remove the threads and place them in the greased baking dish.

In a large sauté pan over medium heat, melt the remaining 2 Tbsp of butter (or ghee/coconut oil). Add the garlic, carrot, celery, onion, and bell pepper and cook for about 10 minutes, until the onion is translucent. Add the ground chicken, garlic powder, salt, and pepper and cook, using a wooden spatula to break up the chicken into small pieces, until the chicken is no longer pink, about 8 minutes.

Remove the pan from the heat, then add the hot sauce and mayo and mix well to combine.

Add the chicken mixture to the baking dish and mix well with the squash threads. Add the whisked eggs and mix everything together until you can no longer see the eggs.

Bake for 1 hour or until the top forms a slight crust that doesn't give when you press it in the middle. Let rest for 5 minutes before serving.

Garnish with chopped scallion and avocado slices.
