Take a flour in a mixing bowl. Add oil, ginger-garlic-chili paste, chopped mint and coriander leaves, salt and mix well. Make a smooth soft dough using water as required like chapati dough, knead it for few minutes and keep aside.
Take a small bowl. Add black pepper powder, chaat masala, cumin seeds, red chili powder, salt and mix well, keep aside.
Make small-small balls from the prepared dough.
Take a ball, dust in the flour for rolling the chapati.
Roll the ball into the thin circle like chapati, spread few drops of oil over the chapati surface and then sprinkle some prepared dry masala powder over it.
Hold the edges of chapati and start making petals till the end, then hold the petals and make a swirl.
Dust the swirl in the flour, press them lightly, roll it again and make like round shape disk/paratha.
Use same process for rest of the dough balls.
Heat the griddle/tawa, place the rolled paratha over it and cook it for few seconds.
Turn the paratha upside down, after 1-2 minutes spread the little oil over it and roast the paratha both side till fluky and golden brown spotted.
Remove it on an observant paper. Pudina Lachha paratha is ready to serve with rayta, subji or pickle.
