Step 1

Cook noodles in a saucepan of boiling water following packet directions, or until al dente. Drain, but keep 2 tablespoons of the pasta water aside in a small bowl to use in the sauce.

Step 2

Heat oil in a large frying pan over medium heat. Add onion, garlic, ginger and chilli and cook for about 1 minute, or until the onions soften. Add the prawns and cook for 2-3 minutes or until opaque. Add the tomatoes and cook for a further minute.

Step 3

Add in the reserved pasta water, parmesan cheese, spaghetti and coriander. Toss for 2 minutes, or until heated through. Season with salt and pepper. Serve immediately.
