First, take 4-5 potatoes and boil them in a pressure cooker on medium heat with half a cup of water or that cover the potatoes. Wait until 3-4 whistles come, then turn off the heat.
When pressure comes down naturally drain the water and pull the potatoes easily. Wait for the cool down, then peel them off.
Now grate the boiled potatoes with a grater or you can mash with your hands.
Add the spices: 1 tsp coriander powder, 1 tsp fennel seeds powder, 1/4 red chili powder, 1/2 tsp garam masala powder, 1 tsp salt or adjust to taste.
Mix all the ingredients well and do a taste test. If you feel less spicy, then add more according to taste.
Now make a roll of spiced potatoes. If your bread slices are short in size, then make shorter potato rolls; if big, then make big rolls. I make big rolls.
Take bread slices and cut off all their edges with a knife.
After that, take some water in a bowl and dip a bread slice into the water for 1 second. If you dip it longer, the bread will break in water.
Now squeeze the excess water from the bread slice with your palms.
Place the potato filling in the middle of the slice.
Now seal it with all its edges from the upper and bottom properly so that the filling is not visible from anywhere. Make a roll.
Heat oil in a pan or kadai on medium heat.
When the oil is heated properly, add the bread roll to it to fry. Fry the roll until it has a light golden texture.
After 1 minute, flip it with from another side with slotted spoon.
Then again, flip it and fry on the other side.
When the roll has a light golden texture, then remove it with a slotted spoon.
Place them on a kitchen paper towel. They absorb the excess oil from rolls.
Serve it hot or warm with tomato ketchup, coriander chutney, and a cup of hot tea.
