On a chopping board, place 2 bread slices and remove it's edges. Next slice them diagonally.
Take one slice and evenly spread 1-2 tbsp of the potato filling on it. Cover the potato stuffed slice with another slice. You have a triangular potato sandwich. Gently press the sandwich.
Take the entire sandwich and gently dip it in besan batter. Don't keep the sandwich for a long time in the batter as the bread tends to break.
Simultaneously, heat oil in a kadhai (or frying pan). Once it's hot, slide the coated sandwich into it.
Fry them on a medium flame, until golden brown on both sides.
Drain them on an absorbent tissue to remove excess oil.
Serve hot with a chutney of your choice or tomato ketchup.
Enjoy with a hot cuppa tea/ coffee!
