First, you take a bowl. Mix the mashed potatoes with the green peas, green chillies, ginger, and all the spices until well combined. Then you divide this mixture into cylinders that are about 2 inches long.
Next, you take each bread slice and trim the crusts off, then you dip it in water or milk for one second. After that, you squeeze it firmly between your palms to remove all the moisture from the bread slice.
Now, you place one of the filling cylinders at the centre of the bread slice, and you wrap it tightly around the filling. You press the edges together to seal the bread slice into an oval shape.
After you have shaped all the rolls you place them on a plate and let them rest for 10 to 15 minutes before you fry them.
When you are ready to fry the rolls, you heat some oil on high heat. Then you fry 2 to 3 of the potato rolls at a time until they are deep golden and crispy. When they are done, you drain them on paper towels. Serve the potato rolls hot with some green chutney.
