In a large mixing bowl, add the chopped kale. Add a dash of sea salt and massage the kale until it becomes softer. (This will make it less bitter to eat and easier to chew.)
Next add the chopped romaine lettuce, pine nuts, chopped chicken breasts, and blueberries.
Add the lemon vinaigrette and toss the salad until everything is evenly coated. Serve.
Add the freshly squeezed lemons, avocado oil, apple cider vinegar, sea salt, and pepper to a small bowl. Using a whisk or the milk frother, mix the dressing together. Whisk until the apple cider vinegar and oil mix together, or with the milk frother stir for 5 seconds, about 2 bursts. Add to the salad.
If you're meal prepping this salad, divide it evenly into airtight containers and keep in the fridge. Will keep in the fridge for up to 5 days.
