Fry the minced meat without fat, mix with the finely chopped onion, ketchup and curry, possibly also salt. Finally add the cheese so that the mixture sticks. Let cool down.
Preheat the oven to 200 °. Thaw the puff pastry sheets.
Then place the meat dough in portions on the puff pastry sheets, seal them to form a packet. Bake for 20-30 minutes, until the puff pastry is a little browned.
