In a medium saucepan over medium-high heat, fry the bacon until crispy, about 5 minutes.
Set aside.
In the same pan, sauté the onion and garlic together for about 5 minutes, or until the onion becomes slightly translucent.
Add the kale to the pan, and stir well so that it begins to wilt evenly, about 5 minutes.
Add the honey, and continue to stir.
Pour in the apple cider vinegar.
Pour in the broth, and bring to a simmer.
Reduce the heat to low, and cook for about 10 minutes, or until the kale is completely tender.
Season with salt and pepper.
