"A great way to eat your vegetables and actually enjoy them. A great alternative to potato chips, veggie chips/straws, or popcorn. Sherry or apple cider vinegar can be used in place of the vinegar if desired."
Place kale leaves in a large resealable bag. Mix olive oil and garlic together in a bowl; pour over kale. Seal and shake bag until kale leaves are evenly coated. Add vinegar to bag, reseal bag, and shake until coated. Spread leaves evenly onto a baking sheet.
Bake in the preheated oven until crisp, 20 to 25 minutes. Season with salt.
