In our gluten free, vegan home (well most of the time anyway!) it's really important I know what I am putting on the table, so Nigel's approach appeals to me.
For the salad you will need root veg - we use a combination of carrots, potatoes, parsnips and sweet potato. I guess you could also use turnip, swede or celeriac. They are then chopped into similar size pieces. Personally I don't peel the potatoes, nor would I peel the carrots if they were fresh enough.
