This is a super simple recipe I copied from the Whole Foods Market website. The grilled kielbasa have such a wonderful flavor. You can even use turkey kielbasa to save on calories and fat. I use more apple just because my kids like the way they taste off the grill. It's okay to let the ingredients sit in the lemon juice mixture for a few minutes. I was concerned about that at first, but it does not overpower or alter the flavor of the dish. I also don't use the skewers. I use a grilling basket - it's much faster!! I serve with couscous.
