Tender lentils slow-simmered with warming turmeric, finished with a sizzling tarka of golden ghee, roasted cumin, and fresh coriander.
Prick the sausages, place them in a pan with a splash of water, and simmer until the fat renders out.
Add the oil, onions, green chilies, and potato and cook until the onions soften.
Cover and cook on low heat until the potatoes are tender and the sauce is thick and deep red.
Halve the rolls and toast them in the pan drippings until warmed through.
Spoon the choriz over the toasted rolls, garnish with coriander, and serve hot.
