Make it Fit (Gluten-Free):
Eliminate the all-purpose flour, and increase the tapioca flour from 1 cup to approximately 1 1/4 cups. (Tapioca flour absorbs more moisture, so when substituting for all-purpose flour, you need to scale it down a little).
Change it Up:
Substitute a different type of your favorite hard cheese for the Parmesan (such as Romano or Asiago).
Use all Queso Fresco (will tone the flavor down as this cheese is very mild), or all Parmesan. You will most likely need to make some minor adjustments on your flour and cooking time, (up and down, respectively), as altering the amount of Queso Fresco will change the moisture content in the recipe.
