I admit, at first I was going to use bottled lemon juice for this recipe, but I am so glad I picked up a fresh lemon at the produce market. There is no substitute for a squeeze of fresh lemon juice! I was inspired by this recipe from 101 Cookbooks, but I made a few changes. The can of beans I had in my cabinet turned out to be white beans instead of chick peas. And while I like kale, I spotted Chinese broccoli at the produce market, and it is one of my favorites, so I decided to use that instead.
