Prepare and set aside your roasted/shredded spaghetti squash, shredded chicken, and cashew cream sauce.
Preheat oven to 375F/176C.
Over medium heat sauté the onions, celery, spring/green onions, and bell peppers for 5-6 minutes until soft. During the last minute of cooking time add in your minced garlic.
Season your veggie mixture with all of the spices listed including the salt and pepper.
In a large bowl combine your veggies, shredded chicken, spaghetti squash, and cashew cream. Add in nutritional yeast if using. Mix well.
Taste the mixture and season to taste if it needs additional seasoning.
Put into a 9in x 9in baking dish and bake for 25 minutes. Optionally, you can broil the top for 1-2 minutes to give it a golden crust.
Garnish with hot sauce and diced green/spring onions.
