A big bag of mixed chard from the market garden. Beautifully colourful and equally as tasty - it has an earthy, sweet flavour very similar to spinach. The stems are really delicious too, but will just need cooking for a little longer. Best blanched or treated in the same way as you would spinach.
Best kept in its bag in the fridge, or if the stalks are long enough you can put them in a vase or large glass of water and keep on the side in the kitchen.
