Salad Vinegars

The nasturtian leaves could be really nice served with a dressing of balsamic vinegar and olive oil. It would make it sweeter and take out some of the peppery flavour. I would use half and half oil and vinegar plus some salt and pepper to taste, herbs could be added for a fresh flavour.
Has anyone else any suggestions on how to use these leaves in salads?
