What's so good about it?
Thought to help prevent heart disease and diabetes, it's also a good source of iron, calcium, fibre, vitamin A and vitamin C.
How to choose
Choose dark greeny-purple coloured broccoli with slender, crisp-looking stalks, tightly packed heads and fresh-looking leaves.
Keep it in the fridge in an airtight bag. Use it before the leaves wilt and the heads discolour - it will keep for around 4-5 days.
Steam or simmer for a few minutes, then toss in lemon juice and zest with a drizzle of olive oil. Add croutons and toasted pine nuts for crunch and flavour.
Slice lengthways down any thicker stalks so they cook at the same time as the heads. You can eat the leaves, so they don't need to be removed.
Did you know?
Broccoli heads are made up of hundreds of small flower buds - if the plant bloomed it would be a mass of tiny yellow flowers.
