Remove the dough sheets from the refrigerator. Preheat the oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer). Melt butter in a small pot. Thinly grease a fat pan (deep baking tray; approx. 32 x 39 cm).
Cut 2 dough sheets in half. 2 1⁄2 Place the dough sheets overlapping in the fat pan in such a way that the pan is completely lined and the dough protrudes slightly at the edges. Brush with some butter. Repeat the process with 2 1⁄2 more dough-sheets and butter.
Place the cheese close together. Cover or spread with remaining pastry sheets and butter as before. Fold in any protruding edges of the dough. Bake in a hot oven for 15-20 minutes.
Meanwhile, for the sauce, peel and finely dice the onion and garlic. Roast the pine nuts in a pot without fat, take them out. Put oil into the hot pot. Fry onion and garlic in it. Sweat tomato paste briefly.
Add tomatoes, bring to the boil. Season with salt, pepper and 1 pinch of sugar. Simmer for about 5 minutes.
Rinse and drain the beans. Wash parsley, shake dry and chop finely. Mix the beans with the tomato sauce and heat. Stir pine nuts and parsley into the sauce and season again.
Cut the pâté into pieces and serve with the sauce.
