Step 1

Bring a pan of lightly salted water to the boil. Add the broccoli and boil for 1 min 30 secs, or until tender. Drain and set aside. Cook the pasta following pack instructions, then drain, reserving a ladleful of cooking water.

Step 2

Heat the oil in a large frying pan, add the garlic clove and fry over a low heat for 2 mins. Remove with a slotted spoon and discard, leaving the flavoured oil.

Step 3

Add the tomatoes to the pan and fry over a medium heat for 5 mins, or until beginning to soften and turn juicy. Stir through the prawns and cook for 2 mins, or until turning pink. Add the harissa and lemon zest, stirring to coat.

Step 4

Toss the cooked spaghetti and pasta water through the prawns and harissa. Stir through the broccoli, season to taste and serve.
