Place a spoonful of the potato mixture on one half of the tortilla, leaving the other half empty, so it can be folded over later. Press the potato mixture with your hand, for easier handling later.* Repeat this step for all of the tortillas.
Pour some vegetable oil into a large skillet. You’ll need just enough to cover the bottom (about 3 tablespoons). Put your taco in the skillet, wait for 15-20 seconds, and gently fold the empty side on top of the potato side.
