Dust flour on a clean tabletop and roll the dough. Every couple of rolls make sure it’s not sticking and dust more flour underneath and on top. Roll it out to 2mm thick so that you get lots of rolls instead of just a couple thick ones. Try to keep it as rectangular as you can. At the very end make sure it's not stuck and dust more flour if necessary so you can roll it with ease.
Paint the melted butter on top evenly and reach every edge.
Place a layer of ham and a layer on cheese on top. Sprinkle with oregano.
Start rolling: first do it carefully so it’s nice and tight and once you have the first 2 complete rolls, you can just push it (still very tightly) so it rolls to the end.
Cut the rolls (I did mine 4cm) and put them on a baking tray lined with baking paper at the bottom (this will help later so the sugar doesn’t stick, you’ll thank me later!) and arrange them nicely. Keep a decent amount of space between them, about a couple of fingers. Let them proof one final time in the fridge for 12 hours. If you want a same-day bake, read the not on the yeast and let them proof 30 minutes.
They go straight from the fridge into a preheated oven at 180°C/350°F for 25-30 minutes or until golden.
