Boil the rice for 25 mins until tender. Meanwhile, heat the oil in a wide, non-stick pan over a medium heat and fry the onions and ginger for 8-10 mins, covered, until softened. Add the courgette, spices and stock, then cover and simmer for 10 mins until the courgette is tender. Remove from the heat.

Blitz the mixture directly in the pan using a hand blender until smooth, then return to a low heat heat and stir in the ground almonds and yogurt.

Submerge the cod in the sauce and cook, covered, for 8-10 mins until the fish flakes easily. Meanwhile, combine half each of the onions, lemon juice, coriander, chilli and banana slices for the salad. Serve half the rice with half the korma and the salad. Leave the remainder to cool completely, then chill to eat another day with the rest of the salad. Will keep chilled in an airtight container for two days. Reheat in a pan over a low heat or microwave until piping hot.
