Prepare the honey-lemon vinaigrette by whisking together olive oil, lemon juice, honey, Dijon mustard, salt, and pepper in a small bowl.

Add mixed greens to a large serving bowl. Top with sliced pluots, cucumber, red onion, goat cheese, and toasted walnuts.

Drizzle with the vinaigrette and toss gently to combine.

Serve immediately. Enjoy!
