Pressure Cook Potatoes to tender. Cool and peel the skin. If you have a potato masher, use it to mash it to a smooth paste. You can use your hands to mash if it is well cooked.
Heat a pan with oil. Sauté the onions, finely chopped green chillies. Fry till the onions are pink. Then add the mint leaves and fry for another 2 mins.
Then, add the cooked mashed potatoes, salt, and garam masala if you are using.
Simmer for 2 mins. Allow it to cool.
Meanwhile, if you don’t like the sides of the slices, trim them.
Then, top a slice with the aloo stuffing, spread well and press another slice over it. Grease both sides with ghee and roast either on hot tawa or in a sandwich maker.
Serve with Tomato ketchup.
