Using a large knife cut the vein out of the kale leaves. Cut the kale leaves into 1" square chunks.
Throw the kale leaves, balsamic vinegar, lemon juice, and maple syrup into a large pan or wok.
Turn the pan onto medium-low heat on the stovetop.
As the pan heats toss the contents of the pan continuously with a couple of forks until the leaves turn bright green but not wilting. This should take less than 5 minutes.
Immediately remove the leaves from the pan and place onto individual plates or bowls.
Top the bowls with crumbled goat cheese, bacon, and nuts if desired.
