My favourite packed lunch for the winter is just to carry a very large flask of soup to work every day. You need some or preferably all of the following in it;
- Protein – either a fish/meat or vegetarian source such as beans or lentils
- A slow release carbohydrate e.g. brown basmati rice, barley, etc
- Loads of vegetables in a spectrum of colours
You don’t need to use more than one or two vegetables at a time but you could also pile in six if you wanted. If you use butternut squash or sweet potato that covers any carbohydrate needs.
