Leeks have a small, bulbous base with a long, leafy stem. They're similar to onions, but have a milder flavor that may appeal to diners who don't like the strong taste of traditional onions. Though leeks are often used as a garnish or for flavoring, they can also be grilled and served as a vegetable dish. Leeks are easy to grow and can be harvested throughout the year in all but the coldest climates.
To prepare leeks, start by cutting off the green leafy tops. Some people may use these tops for flavoring soups or other dishes, but they're generally too tough to eat on their own. Slice the tender white stem of the leek in half, and grill for 11 to 13 minutes on each side [source: Good Housekeeping].
There are a number of ways to season grilled leeks depending on your tastes. Try seasoning with basil and white wine vinegar, or garlic and butter to enhance the natural flavor of the leeks. For a bolder taste, brush with olive oil and sprinkle with red pepper flakes [source: Brown].
