Just make a bread dough to this part. Either you know one or you can easily learn one. If you've got 500g and 7g of plain flour and a dried fast acting yeast respectfully, you have everything you need at a minimum, albeit water. I added some salt, about 5g. Mixed it round in a bowl till it was holding together then put it on a flour covered surface and pushed its edges into the middle until it has a gently moist surface but not at all sticky. The kids were at school so I left it to rest for now

Stick the buns in the oven. Burger smashing time. That's when the onion was added, and garlic. Pound it around and get it all mixed up so it looks like it couldn't stand. Feel free to add your own preference of spice during the process.

If you're doing the potatoes like we did, cut the spuds in wedges. Soften them by steaming or maybe boiling, until the outsides are ready for the insides to be cooked. Season with an agreeable choice. Apply a thin, equal layer of oil, don't let it get too hot just yet.
