What are they?

They're stalks, they're stems, they're about using it all, not just the glamorous bits. About reducing waste, and not throwing nutrients down the drain or dumping them into landfill. Yes people, it's time to Save Our Stalks, Steam Our Stems and Serve Our Shoots. Broccoli stems, in particular, are deliciously tender, and many people (including my mother) actually prefer them to the florets.

Where do they come from?

The same place that kale chips and green smoothies come from: a desire by health-minded people to benefit from greater nutrients and to reduce waste. At NSW's Tomah Gardens Restaurant in the Blue Mountains, chef Sean Moran serves home-grown glossy green broccoli stalks as a vegetable side dish. "The best thing that can happen to a cook is to get out into the garden and grow things," he says. "It's such a nice surprise to learn stalks and stems are so delicious."

A cafe by zero-waste evangelist and designer Joost Bakker specialises in four intense, nutritious broths made from Cape Grim beef bones, fruit and vegetable skins, organic chicken bones and marron and crab shells saved from the kitchens of Rockpool, Attica and the European. Naturally, he calls it Brothl. You choose your broth, then add mussels, bacon, noodles, kimchi, or and/or ''greens and weeds''.

"Stalks and stems are among the most nutrient-dense foods in the world," Bakker says. "A lot of the plant's energy goes into the stem to support the head - and what makes the plant strong, makes us strong."

Seven things to do with broccoli stems

1. Peel, cut into quarters lengthwise and use as raw crudite with a creamy dip.

2. Save them to add with other leftover vegetables into vegetable stock.

3. Cook in chicken stock with two chopped potatoes until tender then whiz into soup.

4. Cut stalks on diagonal and stir-fry with Chinese sausage, soy and hoisin sauce.

5. Pickle sliced stalks in vinegar, salt and sugar, and serve in burgers and salads.

6. Steam until tender and top with a fried egg and grated parmesan.

7. Steam until tender, mash and turn into vegie burgers and fritters.

BROCCOLI STEM NOODLES

Finely sliced into strips, leftover vegetable stalks or outer leaves cook very quickly and retain their goodness.
