- Cut dough into 6 equal pieces. Roll out each piece into a thin 4”c10” rectangle with the wide side facing you. Brush with oil, sprinkled with sea salt and scallions to lightly cover the surface of the dough. Roll like a pinwheel from bottom up, then roll right to left like a snail. Tuck the end in roll that out to a thin circle. Repeat with remaining pieces.
- Heat a grill pan to medium heat. Brush each pancake with a thin layer of oil and grill 2-3 minutes on each side until surface is cooked and grill marks are achieved. Place the pancake into a taco holder or drape over a spoon over a bowl to create a taco shell shape. Repeat with remaining pancakes and keep warm by covering with a clean kitchen towel.
