Potato, Red Onion, Cracked Peppercorns and Rosemary Sourdough Focaccia

We are hosting a group of friends for dinner tomorrow night and wanted to bake a focaccia again to have with our chicken Marbella with peaches. I haven’t made a focaccia with potatoes yet so decided on this one adding the usual red onions, rosemary and cracked peppercorns to it. Nothing fancy but hopefully good.
