For this casserole, we're not using a traditional breakfast burrito fold, we're simply rolling the flour tortillas with the mixture inside. Place the sausage mixture in the center of the tortilla. Take one end of the tortilla and lay it over just far enough to tuck in slightly under the sausage mixture and then pull the mixture towards you. Then roll the flour tortilla to create the burrito. Please refer to the photo labeled as Step 5.
