Boil the pasta in salted boiling water. In the meantime, cut the tomatoes and grapes into halves, remove the seeds from the grapes.

Drain pasta, mix with pesto, let cool. Add the prepared ingredients, mix, put a slide on a dish.
Garnish with sweet pepper slices and orange fillet slices. Sprinkle with chopped onions, drizzle with balsamic vinegar, top with olives.
