In a large skillet or pot bring the olive oil to high heat. Next, add in the sliced garlic and sauté until golden, about 1-2 minutes.
Next, add in the chopped kale, salt, and black pepper and sauté for 5 minutes, mixing occasionally.
Next, add in the vegetable broth (or chicken broth) and balsamic vinegar (or lemon juice) and bring to a simmer.
Cook for 10 minutes, mixing occasionally, or until the kale with garlic and oil is tender.
Serve the kale with garlic and oil with a pinch of crushed red pepper flakes as a side dish with a main entre, or over pasta for a great vegetarian meal option.
