Learnt this from food historian Pritha Sen. Love the simplicity and efficacy of this dish. And its done in a jiffy.

• Parboil potatoes and cut them like you would do for French fries
• Slice beans with a slight slant to each piece
• Finely slice half an onion
• Heat a tsp of oil and sprinkle a quarter tsp of pepper
• Add the onions and the potatoes and mix well
• Slow cook for a few mins and add the beans along with salt to taste.
• Mix well and cover and cook.
• Sprinkle a little water if it sticks to the pan.
• When beans and potatoes are both cooked, remove from pan.
• In the same pan, heat just a little butter and scramble a couple of beaten eggs
• Add the potato and beans back into it and add pepper powder to taste and mix well.

Done! Complements rotis and a bowl of dhal perfectly.
