Cooking for one is a real skill. Leftovers are just you being kind to Thursday you.

Most recipes assume a family, and scaling down is its own craft: what keeps, what does not, how to buy a vegetable you will finish. There is nothing lesser about cooking for one person, and the people who get good at it eat better and spend less than everybody around them. Cooking extra on purpose is the main trick.

Make one thing this week in double quantity and put half aside before you eat. Chilli, rice, pasta sauce, anything that improves overnight. On the evening you have nothing left, you will have done the hard part days earlier.
