So long, sad desk salad! This apple feta salad is your answer to tastier lunches on-the-go, and it works equally well as a fresh, crispy side dish with a savory protein at dinner.
Preheat the oven to 350°F. In a small saucepan, melt the butter over medium heat. Stir in the sugar and pepper. Add the walnuts and toss them to coat, then spread them evenly onto a baking sheet. Bake them until they're lightly browned, about 15 minutes, stirring every five minutes. Let the walnuts cool on a wire rack.
Place the olive oil, white wine vinegar, Dijon mustard, minced garlic, sugar, oregano, salt, parsley flakes, pepper and chopped onion in a blender. Cover and process until blended.
Place the romaine, red leaf lettuce, green apple, red apple and crumbled feta cheese in a large bowl, and toss them with the dressing. Top the salad with the toasted walnuts and serve immediately.
