Heat oil in a kadhai. Add cumin seeds and let it splutter.
Fry now the chopped onion till golden brown. Then add ginger-garlic paste, tomatoes, salt, turmeric powder and chilli powder.
Cook in low-medium heat till the oil separates.
Now add chopped capsicum and potato. Cover and cook till they are soft. Add Maggi magic masala and mix well and cook for a minute. Serve hot with roti and parantha.
Thanks
