Dr Clare Bailey Mosley: Miso Soup with Mushrooms and Prawns

Almost instant and very low-calorie, this is a fast-day life-saver.

It was one of the recipes I demonstrated in our Channel 4 series Lose a Stone in 21 Days. Miso paste has a deliciously sweet, salty, slightly tangy flavour. The prawns add a good boost of protein and omega-3, along with other nutrients, including selenium (which most of us are lacking and is important for the immune system). You can add a handful of young spinach leaves or cooked greens as well. Simply add at the same time as the prawns. Having grown up in Hong Kong, Michael loved this exotic dish, rich in protein and fibre. Miso soup kept Michael going in his early 5:2 fast days.
