Sauté sausage in large skillet until completely cooked.
Remove sausage from pan, saving about 2 tablespoons of the drippings from the sausage.
Keep these drippings in the pan.
Add the almond flour and arrowroot powder to the skillet, and whisk with the sausage fat over medium-low heat, until a paste is formed, working to scrape up some of the sausage drippings.
Pour in about ¼ of the coconut milk, the sage, and paprika at this point, and bring to medium heat, stirring often and scraping up the browned sausage bits.
Add remaining coconut milk, stirring as you go, and bring to light simmer.
Add sausage back in, and simmer until gravy reaches desired thickness
Pour over biscuits sliced in half and serve.
