Peel and grate lauki and squeeze out the juice from the lauki. Do not throw away the water, reserve water to knead dough or for making curry.
In a bowl, add wheat flour, squeezed grated lauki, chopped spinach (palak), coriander leaves, ginger, green chilies, garam masala, amchur powder, jeera powder, oil, and salt. Mix well.
Lauki will ooze out some water hence be careful while adding extra water and make a smooth (but not sticky) dough.Smear little oil on the dough and let it rest for only 5 mins. Do not rest it for more time, the dough becomes very soft.Note: I didn't add extra water for preparing the dough. Make balls from the dough. I was able to get six balls.
Roll the parathas semi-thick/ thin by dusting some dry flour.
Heat a tawa/skillet on medium heat and place the paratha and let it cook. Once you see bubbles, flip onto the other side drizzle some ghee or oil on top.Flip again and drizzle oil or ghee on the other side until they have nice golden spots on both sides. Serve Lauki ka paratha (sorekai paratha) with curd, pickle, raita, ketchup, or any gravy of your choice.
