Wash the tomatoes and cut them into small pieces. Peel onion and garlic. Dice both finely. Heat the oil in a pan. Fry the minced meat in it until crumbly. Fry garlic and onion briefly. Stir in the tomatoes and braise for about 3 minutes.
Season with salt and pepper. Clean, wash, shake dry and chop rocket salad coarsely.
Preheat oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer). Unroll the dough, remove the paper. Roll out into a rectangle (approx. 30 x 55 cm) on a lightly floured work surface.
Spread the chopping mixture over it. Sprinkle with rocket salad and cheese in pieces. Roll up from the long side. Place on a baking tray lined with baking paper. Form into a ring. Press the ends together.
Place an ovenproof glass in the middle. Cut the roll of dough diagonally several times.
Bake in a hot oven for 20-25 minutes. Take out the Tortano and remove the glass. Arrange on a plate.
