In a small glass bowl, warm the honey and the vinegar in the microwave. Stir together until the honey dissolves. Combine the mayonnaise, mustard, onion, parsley, and oil in the pitcher of an electric blender.

Add the honey mixture and blend until thoroughly combined. Chill in the refrigerator until ready to serve.

In a skillet over medium heat, toast the almonds until they are fragrant and browned. Remove from the heat and set aside to cool.

In a large bowl or on a platter, combine the spinach, lettuces, raisins, almonds, and apple slices. Lightly drizzle the salad with approximately half of the prepared dressing just before serving. Store the remaining dressing in the refrigerator.
