Kohlrabi

A relative of wild cabbage, this unique-looking vegetable has been hailed as one of the 150 healthiest foods on Earth. It is most commonly consumed in India, and is a staple in the Kashmiri diet. Pretty much everything on this plant is edible. Fry up the root for some kohlrabi fries, toss the leaves in a salad, or chomp on the crisp, juicy stems for a low-calorie snack.
