Tips and Tricks:

For an optional, but delicious topping: Set aside a small handful of your sliced onions and lightly coat them in coconut flour. Add oil to a small pan and fry the onions until golden. Let them sit on a paper towel when you remove them from the oil and lightly salt.
Sprinkle these on top of the casserole before serving.
