in a large mixing bowl mash 2 potatoes. add chopped coriander leaves and onion.
next is to add the dry spices like chilli powder, garam masala, chaat masala, amchur powder and salt to taste.
combine them well breaking aloo pieces.
now grate the cheese or you can add in grated cheese and combine well.
take small amount of the stuffing and prepare small oval shaped balls. make sure the size is small and fits into your bread slice. keep them aside
take the bread slices and cut the edges from all 4 sides.
roll them flat using chapati roller. roll as thin as possible. this helps to prevent oil from absorbing when you deep fry.
brush the edges with water. you can alternatively dip the entire bread in water and squeeze off the water between your palms. however, it absorbs more oil and you wont get a nice stiff shape like spring roll.
place the stuffing prepared previously and roll them. press the edges to seal them tight.
brush some water around the edges and seal them properly. else the stuffing will be in oil while deep frying.
heat the oil and deep fry the rolls on medium flame.
fry them till they turn golden brown. drain and place on an absorbent paper.
serve bread roll hot with tomato ketchup or as it is.
