Believe it or not, there is a global kale shortage in our near future. (Will our green smoothies—and manicures—ever be the same again?!) Thankfully, there's plenty of agretti, the newest nutrient-packed superfood that's ascending the ranks. Also known as Salsola soda, this tart veggie hails from the Mediterranean, looks like a cross between rosemary and grass, and can be served with salads, pastas, or as side dish on its own. Even if the kale supply doesn't run out, we think it's worth seeking out the green stuff.
