In medium saucepan fry oil in just a dash of cold pressed oil, add garlic then lima beans. Continue until fragrant then add stock, keep on medium heat until beans are soft. Add seasonings, heat through for one minute. Put bean mix through processor until the right consistency is reached. It is important to add flavourings as this soup can be a bit tasteless without them. Adjust the consistency by adding water or more stock if needed.
I haven't worked out the nutritional info, but if you use just a small bit of oil it is quite good for you. If you want to omit the oil try sauteing the onion in a little stock.
