Toss salad greens, cucumber, tomatoes, red onions, olives, and croutons with Honey-Lime Vinaigrette. Evenly distribute salmon on the top of salad and sprinkle with crumbled feta cheese.
Place the lime juice, vinegar, and egg in a blender. Run on low and slowly drizzle in the oil and honey until the mixture is slightly thick. Add salt and pepper and refrigerate for 12 hours before serving.
