Take cleaned and roughly chopped spinach leaves, garlic, green chili, cumin seeds into a mixer grinder and grind them into a smooth paste. Try avoiding water to grind this mixture. If you are unable to make the fine paste, add water spoon by spoon.
Now take a mixing bowl, add whole wheat flour, spinach purée, and salt.
Make a smooth dough out of this and add a tsp of oil. Mix it once so that oil is incorporated well into the dough.
Keep this aside for 15 to 20 minutes. You can make the spinach paratha immediately also.
When you are ready to make these parathas, take the dough and divide it into equal-sized balls.
Take one dough ball, flatten it, and roll it in the dry flour.
Place this onto the rolling surface and roll into thin flatbread.
If you can roll and cook the parathas simultaneously, you can heat the pan while you are rolling the paratha.
Heat a pan and add the paratha once it is hot.
Cook it on medium flame on both sides till it is done.
You can add a tsp of oil on each side while cooking the paratha.
Likewise, make all the palak parathas and serve them with any dal or curry.
