• Cook pasta according to packet instructions - place in a large pot of boiling water and cook for around 6-8 minutes, or until cooked to your liking. Drain.
• Meanwhile, cut broccoli into florets and process together with the stalk part, in a food processor until it resembles rice grains in size. Finely slice zucchini and spring onions. Dice bacon.
• Heat a large frying pan over medium heat. Add pine nuts and toast for 2 minutes, stirring often. Remove and set aside for serving.
• Return pan to the heat and add bacon and cook stirring for 1-2 minutes. Add zucchini and the white parts of the sliced spring onion. Cook for 2-3 minutes.
• Add processed broccoli. Increase heat to high and stir fry for 2 minutes. Add cream and bring back to the boil. Stir in pesto. Add up to 1 cup of hot water to loosen the sauce.
• (If using, add shredded cooked chicken or canned tuna and stir through the sauce).

To serve:

• Divide pasta between serving plates or bowls. Top with the broccoli pesto sauce.
• Sprinkle with pepper, cheese and toasted pine nuts.
