Brush both side of your tortilla with oil. Turn your bowl upside down and place tortilla around it. Cover with tin foil to give your tortilla support and press it around the tortilla so it is flush with the bowl. Bake for about 5 min on 375. Check on tortilla and it should be able to stand on its own when you remove the bowl and tin foil. From there, place back in the oven for another 8 min or so.
