Roasted Kale and Red Onions

Found in a recent Fine Cooking Magazine, this tasty side dish recipe is a perfect combination of balsamic vinegar, kale, and red onion. The side made a wonderful partner to our Roasted Loin Chops with Charmoula.

With only the two of us, we cut the amount of onions and kale in half, the balsamic vinegar and chicken broth by a third, and the remaining ingredients were kept the same. The original recipe is intact below.
