Stir in rice, reduce heat to medium-high and cook, stirring occasionally, until rice is partly softened, 5-7 minutes. Drain and let cool slightly. Preheat oven to 375 degrees.
Add diced tomatoes, saffron, seasonings, and your chosen type of tinned fish (such as mackerel, cod, sea bass, or sardines).
This simple chicken curry uses a tin of tomato soup as a shortcut to create a creamy, mild and slightly sweet curry sauce, not dissimilar to tikka masala. Great served with pilau rice or naan bread.
