Wash and cut drumsticks into 2-inch pieces. Boil them until tender, then extract the pulp using a spoon.
Heat a little oil in a pot. Add ginger, garlic and chopped onions. Cook until they take on a golden brown colour.
Add chopped tomatoes and cook until soft. You can also add other vegetables like carrots and beans if desired.
Add the drumstick pulp, salt, pepper and any other spices you prefer. Pour in water or vegetable broth and bring to a boil.
Reduce the heat and let the soup simmer for about 15-20 minutes. Garnish with fresh cilantro before serving hot.
