Whisk the vinegar, olive oil and salt and pepper in a small bowl.
Slice the apple into matchsticks.
Crumble the Gorgonzola cheese into small pieces.
Place your salad greens in a large bowl and toss with the seeds, pine nuts, cheese and apples, reserving a few of all the add-ins. Adjust the seasoning to your liking. Drizzle a little of the dressing onto the greens and toss gently. Drizzle just enough dressing onto the salad to lightly coat the leaves - not too much. Add additional salt and pepper if you like and scatter the reserved toppings over the salad.
