Gut Bug Soup (Broccoli, Leek & Cauliflower)


Broccoli, Cauliflower & Leek Soup

I've been really trying to increase the diversity of prebiotic foods I've been eating recently, and wanted to combine a whole load of these in one soup! So I've added loads of onion, garlic and leeks to hearty cruciferous broccoli and cauliflower to create a delicious meal for both you and your healthy gut bacteria!
