While I always eat my broccoli stalks one of my kids always bites off the top and leaves the stalks on his plate.

Making broccoli pesto is a great way to ensure that the whole of the broccoli - stalks, florets and even the leaves - is eaten.

Broccoli pesto is a great zero waste recipe that's a great one for batch cooking and can be stored in portions in the freezer.

3. Drain the broccoli and place in a large bowl of iced water to cool. This step isn't essential but it helps to retain the bright green colour of the broccoli.

4. Place the cooled broccoli into a blender or food processor along with the roughly torn basil leaves, mixed pumpkin and sunflower seeds, the juice of a lemon, 3 tablespoons of the olive oil, 2 tablespoons of nutritional yeast and a pinch of salt.

5. Blend until well combined, stopping to scrape the sides down at least once. Pour in the remaining two tablespoons of olive oil, a little at a time, while continuing to blend until you have the consistency you like.

How to serve broccoli pesto

Pesto is traditionally served with pasta. Trofie (a small, twisted pasta shape) is traditional but spaghetti or linguine can also be used. I have used tagliatelle for the photographs here.

Pesto doesn't need to be cooked (apart from cooking the broccoli florets in this un-traditional broccoli pesto recipe). When ready to serve simply stir through your freshly cooked pasta. Usually this will be enough to warm the pesto enough if serving immediately.

If needed you can lightly heat the pasta and pesto in a saucepan - but keep stirring to avoid sticking.
