Preheat the oven to 350 F and line a baking sheet with parchment paper.
To make the dough, add the sweet potato to a large bowl and add the arrowroot starch. Fold until a dough forms. Stir in the garlic powder, onion powder, salt, and nutritional yeast.
For the filling, combine the beef, sauce and seasonings in a small pan set to low heat on the stove. Stir for 2-3 min on low until the sauce is coating the beef. Set aside.
Take about 2 tbsp of dough at a time and roll into a ball. Flatten the ball and add a spoonful of filling to the center. Fold the dough over and form into a slightly flattened ball. Repeat for all of the dough and filling. You should have about 8.
Place the pizza rolls onto a baking sheet and spray with avocado oil. Transfer to the oven and bake for 35-40 minutes, flipping halfway. Remove from the oven.
