Following the hugely successful The CSIRO Low-Carb Diet and CSIRO Low-Carb Every Day, Pan Macmillan released The CSIRO Healthy Gut Diet.
There’s no  doubt the CSIRO leads the way in nutritional research, and has won our trust when it comes to health advice as well as interest from health professionals and bodies in Australia and around the world.


PREPARATION 10 minutes

COOKING 15 minutes, plus resting time

  • 1 tablespoon garlic-infused olive oil
  • 2 zucchini, cut into 2 cm dice
  • 1 stick celery, thinly sliced
  • 1/2 cup (125 ml) lactose-free milk
  • 4 eggs
  • 100 g aged cheddar, crumbled
  • 1 cup baby spinach leaves, trimmed
  • 1/2 cup small basil leaves Reduce
  • 4 slices gluten-free chia and sunflower, bread, toasted

Heat the olive oil in a frying pan over medium heat. Add the zucchini and celery and cook, stirring, for 5 minutes or until softened and light golden.

Meanwhile, whisk together the milk and eggs in a jug and season with freshly ground black pepper.

Reduce the heat to low and pour the egg mixture into the pan. Stir gently for 20 seconds, then leave to cook, untouched, for 8 minutes or until the edges have set firm and the top and centre are still runny.

Preheat the oven grill to high.

Sprinkle the cheddar over the egg mixture, then place the pan under the grill for 2–3 minutes or until the cheese is melted and golden and the centre is completely set when tested with a knife.

Stand for 5 minutes, then cut into quarters and scatter with the combined spinach and basil. Serve each portion with a piece of toast alongside.

You can add 2 cups (270 g) chopped unpeeled sweet potato to the zucchini mixture in the pan – just cook it for an additional 5 minutes to soften. This will add 1 unit of breads and cereals per serve.

Celery is low-FODMAP in small quantities (up to ½ stick) – more than this is high-FODMAP.
