Potatoes are a divisive vegetable but the evidence is mounting that this starchy spud offers a host of health benefits. They’ve been a valuable part of almost every culture for centuries and provide an excellent source of energy for the brain and muscles.

Leeks are a lesser-known cold weather crop that belongs to the onion and garlic family. They are often described as a milder form of onion and garlic. When combined with potatoes, leeks help bring out the overall flavor of the dish.
