Don't throw out your old root veggies, turn them into crisps. Peel carrots, sweet potato (my favourite) and beetroot and slice them as thinly as possible (if you have one of those potato slicing machines, then this is even better). Dry them off with a clean tea towel and coat them with a little oil. Spread them in a thin layer on a baking tray and bake them in the oven for about 6-8 minutes. Season and enjoy!
