For convenience’s sake, there are a number of quick-cooking grains: amaranth, millet, regular oats, quinoa, and teff can all be prepared in less than twenty minutes. For grains that take longer, such as barley, farro, or steel-cut oats, consider cooking a big pot in advance on the weekend so you can simply reheat for your meals throughout the week. Or get a rice cooker—you can buy one for less than £13.
