This is a hearty vegetable soup and is very simple to make. The blue cheese adds to the rich flavour, and looks amazing when served with chunks on top, melting into the goodness of the veges. As with all my recipes I like to give options, so if you dont have any blue cheese handy, or are not partial to it, then leave it out. The vegetables alone make a delicious healthy soup
Cauliflower lacks the green chlorophyll found in other vegetables of its class like broccoli, cabbage and kale, because the florets are protected from the sun by its green leaves during its growth. It does however provide many of the same nutrients of those vegetables. It helps strengthen the immune system and protects against the development of cancer forming cells.
