JLPT N3 Reading

Five years into living alone, I bought almost all my meals. It's not that I couldn't cook. But cooking for one leaves ingredients over, and they end up thrown away. I hated that, so I naturally stopped cooking. Last year I started going to a cooking class at the local community centre. The aim wasn't to learn to cook but to learn 'how to cook for one'. In fact, what the class taught was less about seasoning than the order in which to use up ingredients — a menu that uses one carrot over three days, and so on. After six months, I eat out about once a week. My food costs fell by a third, but even better, I no longer stand at the open fridge wondering 'what do I do with this?' Many people who think they're bad at cooking may simply be bad at planning menus. Q: Why did the writer start the cooking class? — To learn how to cook for one.
