An interesting article in the Washington Post today claims that lettuce is a huge waste of resources. Containing little nutritional value, "Lettuce is a vehicle to transport refrigerated water from farm to table." It is the vegetable responsible for the most food waste. Conclusion: "as we look for ways to rejigger our food supply to grow crops responsibly and feed people nutritiously, maybe we should stop thinking about salad as a wholesome staple, and start thinking about it as a resource-hungry luxury." Wow!
The article's suggested alternative? (somewhat NSFW)
Collard Greens (Gimme gimme gimme some!)
