Heat oil in a frying pan.

Add onions and stir, until it becomes golden brown in colour.

Add masala powder, ginger-garlic paste and tomatoes and stir for a while.

When it becomes a paste format, add water and allow it to boil.

Whe it starts boiling, add the tuna pieces and cook for 5 - 6 mins.

Allow the water to dry up so that we can get this in a semi solid form.

Add soya sauce and coconut milk.

Simmer for 2 mins.
