Consume fresh broccoli as soon as you can as it will not keep for long. To store, drizzle water droplets on the flower heads, cover loosely in damp paper towels and refrigerate. But never wash broccoli before storing in the refrigerator. The excess moisture promotes mould. Do not store broccoli in a sealed container or plastic bag. Raw broccoli requires air circulation. 
Brocollis serve as a healthy raw vegetable. Add them to your salads, pasta, curries and rice. Steam broccoli stalks, add some salt and oil and roast it for a crunchy flavour.
