Metric Beans

Do this once.

Beans are simple, and so is the metric system. Put them together, and eat simply, cheaply, low on the food chain and carbon emission spectrum.

I've written about it before, but that was a while ago, and for new readers, here's the logic: cook a big mess o' beans in the crockpot, and you've invested minimal effort in return for several meals' worth of protein.  

Do this twice.

In case the photos are not obvious enough, here's the recipe:

1000 cc beans (cc= cubic centimeters, because volume's the quickest measure to make)
2000 cc water
Put all this in a crockpot with a metric toss o salt. Turn it on. Wait til the beans are soft before you eat them. 

That's it.
