I make this kind of paratha atleast once a month. The idea for the delicious spring onions and peas stuffing is from Musical's Kitchen.
For the stuffing, I fry cumin seeds in a tsp of oil till fragrant. Then I add ginger paste and chopped spring onions (white and green parts) and saute 5 mins, then go in some frozen peas and other seasonings like salt, pinch of sugar, cumin pwd, coriander pwd, red chilli pwd and amchoor pwd (all per taste). Cook another 5 mins, mashing the peas a little along the way. Cool this mixture and use it to stuff the parathas.
When my dad visits, I always make extra spring onion - peas mixture as he loves to eat it just by itself.
For making the paratha, I roll out 2 equal circles of the regular roti dough, spread the above mix out on one circle, line the edges lightly with water, place the other circle on top and seal the edges together. Lightly press the paratha with my palm, then using a little flour, roll it out a little more. I cook the paratha on a non-stick pan with a little oil on each side until brown spots develop.
