Begin by heating a frying pan at medium-low heat. Add the Olive Oil and crushed garlic.
Cook the garlic until just browned, then add the chopped spinach and stir until spinach is cooked thoroughly.
Next, add bone broth and heavy cream and stir until combined.
When the broth and cream begin to steam, add the Parmesan Cheese, Italian Seasoning, Garlic salt, and Rice flour. Stir until combined and sauce thickens.
