I've made these a couple of times now and they are an absolutely delicious substitute for flour tortillas. Just fold them up with some cheese, taco meat, tomatoes, lettuce, and salsa inside and you have yourself a meal.
Please check out the whole article (Indian Summer Celebration), which includes frying directions, just in case you want to try the more authentic and higher calorie version of this Southwestern classic.
3 cups unbleached flour
1 - 1/2 tbl. baking powder
3/4 tsp. kosher salt
1 - 1/8 cups warm water
Mix ingredients together, knead well for 4 or 5 minutes, adding flour as needed. You should end up with a soft and pliable dough which is no longer sticky. Cover and let rise for 1/2 an hour.
Shape the dough into 8 small balls. Roll out to 1/4" thickness, using your hands or a rolling pin, until each piece is 6" to 8" in diameter. Cook on a hot ungreased griddle for about 2-3 minutes per side, or until browned.
