I buy the food in bulk, cook the food, and freeze them in tray like ice cubes. Remove the pods and put them in ziploc bags to save space. This way, it does "extend" the shelf life.
My freezer is small. I use freezer trays to freeze soups and leftovers and then put them in Ziploc bags. I label them and stack them in freezer to save space. I'll pull some frozen food pods out for a soup and salad lunch during my weekdays when I work. Each pod measures to 1 cup so it's convenient for dieting.
