Moving to California has made me much more aware of water - and when I'm wasting it - than ever before. One biggie is the sink-full of water that I use to wash my salad greens every week. I've finally hit on a win-win solution.
Instead of washing my greens directly in the sink as I usually do, I have started using my biggest mixing bowl. Sometimes I need to do multiple batches if I have a lot of greens, but for the most part, this is just as effective as before.
