Ingredients (Low FODMAP Approved)

• 2 cups torn kale (no stems) and basil, combined
• ½ cup olive oil
• ¼ teaspoon salt (plus more to taste)
• 2 tablespoons grated Parmesan
  • (or nutritional yeast for a vegan version)
• Juice of 1 lemon
• ¼ cup macadamia nuts
  • (or walnuts, pecans, or Brazil nuts; see notes below)

Ingredient Breakdown: Gentle Choices for Your Gut

Kale and basil: The perfect balance

Kale adds:

• Fibre and antioxidants
• A slightly earthy flavour

Basil brings:

• Freshness and aroma
• That classic pesto taste

Together, they create a softer, more balanced pesto that’s easier to tolerate.

Olive oil: Smooth and heart-healthy

Extra virgin olive oil provides:

• Healthy fats
• A silky texture
• Anti-inflammatory compounds

Macadamia nuts: A low FODMAP favourite

Macadamia nuts are naturally low in FODMAPs and offer:

• Creaminess
• Mild flavour
• Good fats

Alternatives

You can also use:

• Walnuts
• Pecans
• Brazil nuts

👉 Just keep portions moderate, as FODMAP levels can vary depending on quantity.

Parmesan (or nutritional yeast)

Parmesan is low in lactose due to its ageing process, making it generally well tolerated.

For a vegan version:

• Nutritional yeast adds a similar “cheesy” flavour
• It’s also naturally low FODMAP

Lemon juice: Bright and refreshing

Lemon juice enhances:

• Flavour balance
• Freshness
• Digestive ease
