Preheat oven to 375°F. Line 2 baking sheets with parchment paper and set aside.
Add mashed sweet potatoes, tapioca starch, cassava flour, nutritional yeast, salt and 1 1/2 tablespoons of olive oil to stand mixer and mix until dough forms.
Separate dough into 6 equal balls and set aside until filling is done.
Filling
Heat 1 tablespoon fat/oil in skillet over medium heat.
Add onions and saute for 2-3 minutes until they start to turn translucent.
Add mushrooms and saute another 5 minutes or until mushrooms are soft.
Next, add ground beef and cook until done. Remove from heat and drain grease.
Add cooked bacon to beef mixture. Set aside.
Calzones
Flatten each dough ball into a circle that is about 1/4 inch thick.
Add 1/6 of filling to half of each dough circle, folding the other half over the filling and seal the edges.
Using a pastry brush, spread 1 tablespoon of olive oil over the tops of the calzones.
Bake in preheated oven for 30 minutes or until edges are golden brown.
Allow calzones to cool a few minutes and then enjoy!
Notes
* I use Otto's Naturals Cassava flour. If you use a different brand, you may have to adjust the amount to get the desired results. I have found that not all brands are created equally.
