Cook pasta according to packet instructions. Ensure to season the water with salt. About 1 tbsp.
Whilst pasta is cooking, mix prawn marinade with prawns and set aside.
Once pasta is cooked to al dente, drain and reserve ½ cup of pasta cooking water.
Saute marinated prawns with 2 tbsp of olive oil on a large, non-stick pan on medium/high heat. Cook for 1 minute.
Squeeze in lemon juice, stir for 10 seconds then mix in cooked pasta and reserved pasta cooking water. Stir thoroughly for 1 minute. (Note 2)
By now, the pasta cooking water should have been mostly absorbed.
Turn heat off, mix in parsley and season with salt and pepper to taste. I like to go heavy on the pepper.
Serve immediately, with a wedge of lemon.
