Prepare Nduma: Peel and cut nduma into bite-sized cubes. Rinse and set aside.

Heat oil in a large pan over medium heat. Add onions and fry until golden brown (about 5 minutes).
Stir in chopped tomatoes and cook until they break down into a sauce (about 5-7 minutes).

Add nduma cubes, water, Royco cube, paprika (optional) and salt. Stir well, cover, and let simmer for 20 minutes or until nduma is soft and tender. Add more water if needed to achieve desired stew consistency.

Garnish with coriander (dhania)

Serve: Serve hot with rice, chapati, or as a side dish.
