First cut the slices of bread, arrange them on the baking tray lined with parchment paper and toast them at 200 ° C in the oven in the grill mode for a few minutes, just long enough to brown them.
Place a thin slice of pecorino on each slice of bread and put in the oven for a few more minutes, so that the cheese starts to melt.
Add the lard over the pecorino, wait until it starts to melt with the heat of the bread, then season with pepper, rosemary and a little honey.
The crostoni with lard and pecorino are ready, serve them immediately.
