I never understood why arugula was a food until I grew it. It is intense and bitter, why would people eat it? When you grow it yourself, you just throw down some seeds where it gets some rain during the winter. Then you get massive amounts of it in the spring, and it is all bug free. Without really doing anything. If I had to grow all my own food, then I think I would probably end up eating a lot of arugula. Plus it tastes better when its freshly picked, not just pure bitterness.
