Add the sliced onion and fennel, stir well and cook over a low heat for around 10 minutes until softened. Add the garlic, stir, and cook for a further two minutes.
Add the romanesco florets and continue to stir fry for 10-15 minutes until softened. You can leave it with a little crunch, or cook it until soft depending on your preference.
In the meantime cook the linguine according to the packet instructions.
When the romanesco has started to soften stir through the chickpeas, lemon juice, parsley, pine nuts and chilli flakes if using. Season to taste.
