Rinse, peel and then grate lauki in a bowl. About 2 cups grated lauki. Add Red chili powder turmeric powder,coriander powder,Kashmiri red chili powder and 1 tsp sesame seeds,sugar and salt as required.

Mix everything very well.
Then add 2 cups whole wheat flour and 1 tbsp oil.
First mix the the flour with the rest of the mixture. Start gathering the mixture and kneading to a smooth dough.

Don't add any water while kneading. The juices from the lauki is enough to knead. In case the dough becomes sticky, then add some more flour and knead again.

Take a small to mediums sized ball from the dough.
Place it in a tray or box containing whole wheat flour.
Take the dough ball on the rolling board and begin to roll it with a rolling pin.

Place the rolled lauki paratha on a hot tawa When one side is partly cooked then flip it.
Spread some oil or ghee on the partly cooked side.
Flip again and spread some oil or ghee on the second side.
Flip again a couple of times. Also while roasting press the sides of the paratha so that the edges are cooked well.
