They have lots of stringy roots and big, hard-looking shells on them that people don't know how to peel or prepare, but I've never met a veggie I didn't like, so [the challenge is] getting people out of their culinary rut and into trying new things.

Kohlrabi may be the new kale, a lot of chefs are working with it, so it's well-positioned for trending in 2015. It's kind of ugly, and has these big shoots coming out of it, so most people don't know what to do with them.

Just noodle it, i'm absolutely in love with the spiralizer. You can make pasta out of any of these veggies.

Some of the root veg you may have to cook a little first, getting that hard peel off, often works best if you cut in quarters and then peel from there. And if you still need help you can probably find a YouTube video on how to cut and prepare any of these vegetables.

Turn it into a noodle, turn it into a chip, turn it into a fry, there are so many other ways to make them besides steamed and mashed. And all of these are just fantastic roasted in the oven; nothing can go wrong with a little extra virgin olive oil and sea salt.
