What is the shelf life or expiration date of these meals?

As we use higher quality ingredients than other shelf-stable meals and add no preservatives, our meals are best enjoyed within a year of purchase, though many of our customers continue to store (and eat) their meals well beyond that if stored in a cool/dry place. The included packets (ranch, mayo, etc...) have a manufacturer stated shelf life of 180 days so just make sure to test any condiments before putting them on your meal if you hold onto them longer than that.
