I also made several very yummy meals using the broccoli leaves themselves.
I snipped them off with scissors at the base of their stems, making sure not to ever take more than 1/3 of the leaves from any given plant.
Then I mixed them up with rapini, spinach, chard, kale, etc. The broccoli leaves were among the sweetest in the mix.
