Mix sour cream and cheese. Chop olives finely, dice tomatoes finely. Cut salami into small cubes, ham into fine strips. Halve the sourdough. Stir under one half of tomatoes and olives, season with pepper. Fold salami and ham into the other half.
Fill the spaces between 2 baguettes with the olive mixture. Spread pine nuts on top. Fill the remaining baguettes with the salami and ham mixture and garnish with thyme. Put the breads on a baking tray. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 10-15 minutes
