Unroll the pizza dough on a baking tray and press it a little flatter (approx. 32 x 38 cm). Spread tomato sauce on top. Wash and slice the tomatoes. Drain the olives.
Finely grate the cheese. Spread tomatoes and olives on the pizza and sprinkle with cheese. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 20 minutes. Shortly before serving, clean, wash and pat dry the rocket.
Cut the ham slices lengthwise into thirds. Wrap 1 strip of ham around each of several rocket stems. Cut pizza into pieces and arrange with ham rocket rolls.
