Background

It's become widely recognized that a deep colour is a good indication that a vegetable is good for your health. You can't get much deeper in colour than beetroot and, of course, it is nowadays regarded as a superfood. But this Celeriac, Beetroot and Potato Soup isn't just really healthy - it's warming, filling and delicious too! Here I've made it in the pressure cooker but if you don't have one just use a heavy based pan and simmer for about 35-40 minutes, stirring regularly. During the winter months it's great to take with you in a flask to have when watching outdoor sports.
It works out at less than 100 kCal per portion, even less if you substitute swede for the potato.
