I love pre-packed single servings, not just for the novelty, but because it is soo convenient for working adults and school going kids.
There is the canned and processed items like cereal, drinks, cheese & crackers. Items that do not need refrigeration and can keep for several months.
There are the frozen items that can keep for a month or so in the fridge. Items like chip & dip, sliced frozen fruit and soup.
Then there are freshly prepared items like salads and fruit & vegetable dipping sticks. All packed in disposable containers. No prep, just eat and throw.
