To start, wash your salad greens if they are not pre-washed. Rinse them well in a salad spinner or a colander.
Shake the colander or salad spinner well.
Dump the washed greens onto an absorbent towel and blot any excess water from them.
Leave the greens scattered on a dry towel to air dry a bit as you prepare the rest of the ingredients
Next, you will prepare the toasted walnuts.
Preheat the oven to 350 degrees
In a small bowl, microwave the butter to melt it, about 20 to 25 seconds.
Add the nuts and stir them to coat.
Line a small baking sheet with aluminum foil or parchment paper for easy cleanup.
Scatter the buttered nuts on the foil or parchment.
Bake the nuts in the preheated oven until they are browned and fragrant. This should take about 7 to 10 minutes.
Pay close attention to the nuts, and do not walk away for more than a moment or two. They can burn very quickly.
Stir the nuts and turn them from time to time during the baking time.
When the nuts are toasted, remove them from the oven and allow them to cool on the pan.
Next, you will prepare the apple juice vinaigrette.
Measure the oil, apple juice, apple cider vinegar, honey, lemon juice, salt, and pepper into a one pint mason jar with a tightly fitting lid.
Screw on the lid and shake it well until all the ingredients are fully combined. If you want to, you can use a food processor or blender to mix this all up.
Slice the apples in half and remove the cores from the apples
Slice the apples into very thin slices
Put the sliced apples into a bowl and sprinkle the 3 tablespoons of lemon juice all over them.

Use a large salad bowl and layer in the salad greens with the apple slices, walnuts, dried cranberries, and feta cheese.
Immediately before serving, toss the salad with the apple juice vinaigrette salad dressing.
Toss the salad with tongs and use as much dressing as you desire.
Store leftover dressing in the refrigerator for up to 3 weeks.
