Put flour in a kneading bowl, make a little space and put the yeast, sugar, salt, oil and hot water.
An elastic dough is obtained.
Leave to rise for about an hour.
Break pieces of dough, knead a little and spread with a rolling pin.
On one side of the dough put a piece of bacon and a piece of cheese.
Cover the filling with the other side.
The rest of the dough is made into buns.
Put the pan in the oven at 170 degrees until the buns and wallets are nicely browned.
