Prepare the noodles as per packet instructions.
To make the paste: Place all the paste ingredients into a blender or the bowl of a food processor and blend until smooth
To cook the monkfish: Heat a little oil in a large pan on a medium high heat, then add half the butter. Season the pieces of fish then add four of them to the pan and cook until golden brown on one side, then gently turn the fish over and cook on the other side. This will take about 8-10 minutes in total. Remove from the pan and keep warm while you cook the rest of the monkfish. You will know they are cooked when they lose their translucent or raw appearance. Keep warm while you cook the vegetables and make the sauce.
To cook the vegetables: Rinse the pan and add a little oil. Then stir-fry the pepper and scallions. After 2 minutes add the garlic and bean sprouts. Cook for another minute then remove from the pan.
To cook the laksa paste: To the same pan add a little oil and the laksa paste. Stir for a minute then add the coconut milk and cook until the coconut milk thickens – 3-5 minutes. Add the vegetables to the pan, stir gently through the sauce. Taste and season. Cook for 1-2 minutes to heat the vegetables. Just before serving stir through the juice of 1 lime.
To serve: Divide the noodles between four bowls. Serve two pieces of fish per person and spoon over the vegetables and sauce. Sprinkle over some coriander leaves and serve with some limes wedges on the side.
