STEP 1Boil a kettle and pour water into a large pot over a high temperature. Add a good pinch of salt and add your pasta. While the pasta is cooking, heat your olive oil in a large pan. Throw in your cherry tomatoes and cook for three minutes stirring constantly. Add your prawns, garlic, chilli, lemon zest, half of your lemon juice and the capers. Cook until prawns have turned a lovely orange colour.
