Certain foods are more sustainable than others and, over at Earther, our friend Brian Kahn has been trying to save the world by adhering to a fairly strict, mostly plant-based diet. I have been helping him with a few recipes, because I am nice like that.

When it comes to long-term food storage, the freezer is one of the most useful tools in your kitchen, but it's not as simple as throwing food in a container and letting it chill. To make sure your food freezes fast with minimal damage, freeze it flat.

Whether you're dealing with leftovers, or planning your meals ahead of time, there's a better way to freeze your grains. Save your Tupperware for something else and reach for a plastic freezer bag instead.
