Prepare a dressing from raspberry vinegar, agave syrup, mustard, a little water and oil.
Wash the grapes and cut them in half. Roughly chop the walnuts, roast them in a pan without fat and then dust with cinnamon.
Wash the salads and spin dry, chop them bite-sized and arrange on a platter. Spread the grapes and walnuts on top, add a little pepper and drizzle the dressing over it.
