Cut the tomato in a fan shape on the side - with a 1cm recess on the lower side - so that the tomato stays in one piece and can be pulled apart like a fan. Set the tomato aside.
Halve the mozzarella ball and cut into even slices.
Take the tomato and put a slice of mozzarella in each partition and coat it with pesto (from the health food store or Momo`s pesto (see other recipes from me).
Place the drained rocket next to the tomato fan as a pile and season the entire salad with olive oil, balsamic vinegar, salad spices, salt and pepper.
Finally, drape the basil sprig in front of the tomato fan.
