My freezer used to be a museum of unlabelled boxes. Now everything goes in as a single portion with a name and a date, and I can find dinner in under a minute.
Big bags of nuts and dried fruit are good value, but eating straight from them is a guessing game. On Sunday afternoons I divide one into small jars, and it takes ten minutes.
A soup is the easiest thing to portion badly. This red lentil version is written for six bowls, and the trick that made it work was measuring the finished pot with a ladle.
