For the salad, wash the rocket, cut the feta cheese into small pieces or crumble it. Chop or crumble the walnuts. Quarter the cherry tomatoes and put everything in a bowl, fold in the cranberries.
For the dressing, stir together olive oil, balsamic vinegar, honey, mustard and a pinch of salt until you get a creamy dressing. Add a little more honey or mustard to taste. I like it a little sweeter.
I always put the dressing over the salad just before serving.
