In a large skillet, heat the oil over medium heat. When it starts to shimmer, add the garlic and stir until fragrant, about 30 seconds.
Add the kale and balsamic vinegar and stir until the kale turns bright green, but hasn't wilted yet about 2 minutes.
Remove the skillet from the heat and mix in the cranberries, walnuts, and feta. Add salt and pepper and serve warm.
Notes
Do Ahead or Delegate: Remove the kale stems and rip the leaves into bite-sized pieces, mince the garlic, chop the walnuts if necessary.Like this recipe? Check out The Scramble's family-friendly meal plans to see just how simple getting dinner on the table can be!
