Boil the potatoes in a cooker. Let them cool down, peel them and then mash with hands.
Now take a pan and pour 1 table spoon oil into it. Once the oil heats up then put green chilli, ginger and coriander powder. Roast them and them put mashed potatoes into it along with amchoor powder, garam masala and salt. Mix the ingredients well. The potato filling is ready. Divide it into 16 equal parts and roll it into a cylindrical shape.
Now cut the hard corners of all the bread slices. Take a bowl with water and dip the bread into it. Press the soaked bread with hands to squeeze out the water from it. Put the potato roll on the bread and close it from all the sides.
Now take a pan and heat oil in it. Put this bread roll into the pan and fry it. You can fry 3-4 bread rolls in one time. Fry the bread roll till it turns brown and crispy from all the sides. Spread a napkin on a plate and take out the bread roll on it. Make more bread rolls in the same manner.
Serve the bread rolls with green chutney or sweet chutney or tomato ketchup.
