Step 1

Cook the penne in a large saucepan of boiling water following packet directions or until al dente. Refresh under cold water. Drain well.

Step 2

Meanwhile, heat the oil in a large frying pan over medium-high heat. Cook the prawns for 2 mins each side or until prawns curl and change colour. Transfer to a plate. Add the chorizo to the pan and cook, stirring, for 3 mins or until golden brown. Remove from heat.

Step 3

Return the prawns to the pan with the penne, pesto, olive, bocconcini and chilli, if using. Season and toss to combine. Sprinkle with parsley and serve immediately.
