Mix flour, water and half the salt. Knead 5 minutes until smooth, divide into six balls, cover and rest 30 minutes.
Wash and thoroughly dry the leaves and herbs. Chop them and the scallions finely. Toss together. Keep the salt separate until each bread is ready to fill.
Roll one ball to a thin 9-inch round. Toss one-sixth of the greens with 1 teaspoon oil and a pinch of the remaining salt and pepper. Pile along the middle, leaving a border.
Lift the two long sides over the greens. Pinch together along the center, squeeze out trapped air, seal the tips and pat gently into a thin oval. Repeat, seasoning each portion just before filling.
Heat a dry heavy skillet over medium-high. Cook seam-side down for 2–3 minutes, flip and cook another 1–2 minutes until both sides have brown spots and the dough along the seam is cooked. Stack under a towel and serve warm.
