01 - In a dry skillet over medium heat, toast pecan halves for 3 to 4 minutes, stirring frequently until fragrant and lightly browned. Remove from heat and allow to cool.
02 - In a small bowl or jar, whisk together olive oil, apple cider vinegar, maple syrup, Dijon mustard, minced garlic, salt, and black pepper until thoroughly combined.
03 - Place chopped kale in a large mixing bowl. Drizzle with one teaspoon of the vinaigrette and massage the leaves gently with your hands for one to two minutes until they darken and soften slightly.
04 - Add toasted pecans, dried cranberries, thinly sliced red onion, apple slices, and crumbled feta cheese (if using) to the massaged kale.
05 - Pour the remaining vinaigrette over the salad and toss thoroughly until all ingredients are evenly coated.
06 - Serve immediately, or let the salad sit for 10 to 15 minutes to allow flavors to meld fully.
