To make the dressing, in a small bowl, whisk together the olive oil, balsamic vinegar, lime juice, honey, and soy sauce. Season with salt and pepper. Set aside.
In a small pan, heat the butter and sugar. When the mixture begins to darken and caramelise, add the apple and cook for 4 minutes. Set aside.
In a large bowl, combine the greens, avocado, smoked salmon, mushrooms, almonds, blue cheese, caramelised apples, and, if desired, rose petals. Toss lightly with the dressing and serve.
