Start this recipe by marinating the cherry tomatoes for 1 hour. Place the halved tomatoes into a bowl with the olive oil, balsamic vinegar, honey, garlic, salt and pepper and oregano and mix together well. Allow to infuse for 1 hour. When ready, you can put the salad together. Place the rocket leaves and grilled aubergine slices into 2 deep salad bowls. Arrange 3 slices of serrano ham onto each plate. Spoon over the marinated tomatoes and all their juices and toss over the walnuts. Finally serve the buratta on top split open.
