Remove the Kawan paratha from the freezer and keep your working counter ready. Let the paratha thaw for a couple of minutes in the open, but not any longer as they will become sticky.
Take 1 paratha and dust flour on the rolling board and on the paratha too. Roll it evenly all over. Work on them one by one while they are cool.
Take about 4 tablespoons of the peas filling and spread all across the rolled paratha, leaving half an inch on the side. Spread some slurry around the edges of the rolled out paratha.
Begin to roll from one end, tightly to form a uniform log until you reach the other end. Secure the edges and seal well.
Wrap this log firmly with plastic wrap and refrigerate for 30 to 60 minutes. Work with other parathas one by one similarly and refrigerate all. If you have the time, freeze them for an hour or even longer if it works. They slice way better if frozen for some time.
Preheat the oven at 400F and line a baking sheet with parchment paper.
Remove the logs when ready to bake and slice them equally about an inch wide with a sharp knife and arrange on the lined tray leaving enough space.
Brush some butter uniformly on all the pinwheels before placing the tray in the oven.
Bake at 400F for about 20 to 25 minutes until well done and light golden brown. Do check both the sides regularly to avoid any burning.
Serve the Matar Kachori Pinwheels with sauces and chutney(s) of your choice.
