Cut up cauliflower into 2-inch florets, place them on a baking sheet with diced onion and celery with the almond flour, poultry seasoning, salt, and pepper added.
Roast at 400° for 20 minutes or until the cauliflower is tender when pierced with a knife.
In a saucepan, bring the chicken broth and cornstarch to a boil, it will thicken into a sauce.
Pour the sauce over the vegetables and serve.
*the almond flour isn't critical, but it gives the cauliflower a nice nutty flavor.
