Preheat the oven to 350 degrees F. Lightly grease a 9x13 glass baking dish with coconut oil. Cut the Chebe biscuits in half so that you have a top and bottom. Layer the biscuit pieces in the bottom of the pan.
In a large cast iron skillet, cook the pork sausage over medium to low heat. Remove the sausage and drain the fat into a large saucepan.
Add the homemade broth, tapioca flour, and salt and pepper to taste to the leftover fat. Bring the mixture to a boil over medium heat. Whisk until the gravy thickens. Remove from the heat and stir in the cooked sausage.
Pour the gravy over the biscuits that are layered in the pan. In a separate bowl, whisk together the eggs and optional garlic salt. Pour over the gravy. Sprinkle on the optional cheese shreds.
Bake for 35-40 minutes. The casserole should be lightly browned around the edges and not jiggly. Let it set for a few minutes before cutting and serving!
