Step 1: Prepare the Vinaigrette

1. In a small bowl or jar, combine the olive oil, balsamic vinegar, honey, Dijon mustard, minced garlic (if using), salt, and pepper.
2. Whisk thoroughly or seal the jar and shake vigorously until well combined.
3. Set aside to allow the flavors to meld while you prepare the salad ingredients.

Step 2: Toast the Nuts

1. If using raw nuts, place them in a dry skillet over medium heat.
2. Toast for 5-7 minutes, stirring frequently, until fragrant and lightly browned.
3. Remove from heat immediately to prevent burning and let cool slightly.

Step 3: Prepare the Apples

1. Wash the Honeycrisp apples thoroughly.
2. Core the apples and slice them thinly (about ⅛-inch thick).
3. For presentation and to prevent browning, you can toss the apple slices with a tablespoon of lemon juice.

Step 4: Assemble the Salad

1. Place the mixed greens in a large salad bowl.
2. Add the sliced red onion, dried cranberries, and most of the toasted nuts (reserve some for garnish).
3. Arrange the Honeycrisp apple slices on top.
4. Sprinkle with crumbled feta cheese.
5. Drizzle with about half of the prepared vinaigrette.
6. Gently toss everything together just before serving.
7. Top with the remaining nuts and serve with extra dressing on the side.
