  1. Heat the oil in a large saucepan over a medium heat and fry the onion for 5 mins to soften. Add the cornflour and fish stock, bring to a simmer and turn the heat to medium high. Stir in the soft cheese and frozen fish pie mix, along with the sweetcorn. Cover and bring to a simmer and cook for 5 mins. Stir in the king prawns, peas and spinach and season well with pepper.
