Meanwhile, preheat the oven at 190 deg C.
After resting period, knead the dough again for 1 minute.
Divide the whole dough into 4 parts.
Take one part and start rolling over a dusted rolling board to make a 6-7 inch oval shape.
Cut it into two halves (not lengthwise) using a knife.
Hold one half in palm and grease the straight edge with water either by finger tip or a brush.
Join the edges to make a cone and press down gently the joint area to seal well using finger tips.
Now fill the cavity with 1-1.5 tbsp stuffing and gently press down the stuffing inwards.
After that, grease the inside edges with water by finger tips.
Bring all the edges together and seal properly.
Keep on a baking tray lined with parchament paper and cover by a kitchen towel.
Make similar samosas from the rest dough and stuffing.
Place all the samosas over the baking tray keeping space in between.
Brush each samosa with oil and bake for 35-40 minutes at 190 deg C.
Transfer to serving platter and serve hot with ketchup or masala chai !
