Briefly toast the pine nuts in a pan without adding any fat.
In the meantime, prepare the dressing. To do this, briefly puree 6 - 8 strawberries, depending on size (I don`t like it too fine, but chunky). Mix with the raspberry vinegar and mustard. Stir in the olive oil. Season to taste with pepper and salt, add thyme and, if available, wild garlic pesto can also harmonize nicely.
Cut the spring onions into rings and slice the remaining strawberries and add to the salad. Mix with the dressing.
As an accompaniment to the burger, baguette roasted in olive oil or asparagus, it is very tasty.
