As a single guy you may get tired of buying vegetables because they spoil on you.
If that is the case, two vegetable staples that you can keep longterm for those times when you want a salad but you don’t have your favorites, are carrots and cabbage, they last for many weeks and in a pinch they can be shredded together for a salad with dressing, or a lazy man’s quick coleslaw.
Remember that milk freezes fine so you can save a little money by buying larger, and in the newest refrigerators that keep food at a dependable 36 degrees all fresh foods last for a very, very long time.
The colder your refrigerator the better, my fresh milk lasts for days past expiration and my lettuce lasts for a couple of weeks.
Milk only keeps for a couple months frozen.
We keep our refrigerator at just above freezing. We turn it down until the milk on the top shelf starts to freeze; it turns slightly slushy. Then we carefully nudge the dial up until the milk just stops freezing.
You’re right. At temperatures like that, food keeps a long time.
A good option for a single person for vegetables is bags of frozen vegetables. They can often be had at a great price on sale and they heat up very easily in the microwave and you only use what you need to.
And the quality of the brand name frozen veggies is usually pretty good, especially the peas, carrots, and corn.
