In a large bowl, combine the mixed greens (radicchio, endive, and lamb's lettuce).
Add the viola flowers, toasted pumpkin seeds, crumbled Bergkäse, and sliced apples.
In a small bowl, whisk together 3 tbsp pumpkin seed oil, 1 tbsp apple cider vinegar, 1 tsp honey, salt, and pepper.
Drizzle the vinaigrette over the salad and toss gently to combine.
Transfer the salad to a serving bowl or individual plates.
Enjoy your Austrian-inspired salad with a beautiful and delicious floral touch!
