Preheat oven to 400 degrees. Lightly spray a 9 inch pie pan
In a large mixer bowl whisk together the coconut flour, salt, baking powder, xanthan gum, garlic powder, and onion powder until fully combined
Add the eggs and beat on low about 10 seconds to moisten the dry ingredients. Increase the speed to medium and beat on medium for about 30 seconds or until smooth
Scrape down the sides of the bowl if needed. Add the oil and beat on medium for about 30 more seconds or until fully combined and smooth
Scrape down the sides of the bowl again and push all ingredients to the center of the bowl. Spread a thin layer of the batter over the bottom of the prepared pie pan (about a half cup) Make sure the bottom of the pan is fully covered with the batter
Stir the filling mixture to make sure it is fully combined. Spread the filling over the bottom layer of "crust"
Spread the remaining batter evenly over the top of the filling. Bake at 400 degrees for about 20 minutes or until golden around the edges. Allow to cool for about 15 minutes before serving
