Best thing about green onions is that they hit that sweet spot of (1) adds great flavor to almost anything, and (2) incredibly easy to grow. On point #2, you can be the worst ever at gardening, stick some of these in the ground, and still end up with a never-ending abundance. Once you start, you never have to shop for them again. Anytime you need some, you've got fresh ones to harvest at any given moment.
