Place the walnuts in a dry skillet over medium heat. Stir them constantly for about 5 minutes until they are fragrant and slightly browned, then remove them from the heat to cool completely before adding them to the greens.
In a small bowl or a glass jar, combine the extra virgin olive oil, apple cider vinegar, honey, salt, and pepper. Whisk or shake the mixture vigorously until the honey is fully incorporated and the dressing is smooth and emulsified.
Wash and dry your pears thoroughly. Slice them into thin wedges, removing the core and seeds as you go. To keep them looking fresh and bright on your Christmas table, you can lightly toss them in a teaspoon of lemon juice to prevent browning.
Place the mixed greens in a large serving bowl. Add the pear slices, cooled toasted walnuts, and dried cranberries, then drizzle the dressing over the top. Gently toss everything together so the leaves are lightly coated, and sprinkle with the crumbled feta cheese right before serving.
