Knead a stiff dough with the atta, salt, 1 tbsp. oil and required quantity of water. Keep aside for an hour.
In a bowl, mix together the onions, green chilies, tomatoes, coriander leaves and pepper powder. Keep aside.
Make 4 equal portions of the dough. Roll out each portion into a large circle. Place some of the stuffing in the centre, followed by little of the beaten egg.
Fold the parathas from all the four sides like an envelope. Heat 1 tsp. oil in a tawa / griddle and shallow fry them one at a time on both the sides till light golden in colour.
Make similar parathas in the same way and fry them till done. Serve them hot with any side dish or pickles.
