Melt the coconut oil in a wok or large frying pan over a medium to high heat. Chuck in the onion, courgette, aubergine and garlic. Fry, stirring regularly, for 4-5 minutes until the vegetables are just softening. Sprinkle in the smoked paprika and add the tomato puree, the chunks of monkfish and the kidney beans. Continue to stir-fry for 1 minute before pouring in 150ml water. Bring the liquid to the boil and simmer for 2 minutes, or until you are sure the fish is cooked through. This can be tested by pulling out one of the thickest pieces and cutting it in half to make sure it has turned from raw, pale flesh to cooked bright white. When you are happy that the fish is cooked through, turn off the heat and stir in the ground almonds and chopped parsley, if using.
