onions, mushrooms, garlic, cheese and bread a good combination!

on the top. It sounded good to me until I saw that. Do you add ketchup?

The only thing I'd add is some freshly grated nutmeg, it does magical things to mushrooms.

During the Year of the Lockdown, when I couldn't get to the store, I was down to breadmaking stuff and onions. So I remembered the ancient Egyptian prayer for bread, beer, and onions and decided to give the bread and onions a try. I baked the bread, sauteed a sliced onion, and put it on the bread as an open faced sandwich. It was so much better than I thought it would be.

I passed on the beer. Egyptian beer always seemed like kind of a gritty affair, fermented watery porridge sieved through papyrus reed cloth, I'd have passed on it even back in the days when I chanced drinking once or twice a year.

It's pizza crust topped with mashed potatoes and cheese. I used to get it at pizza joints when I lived in Western PA and liked it so much that I started making my own. I make it from scratch, but it can easily be made using prepared pizza shells and instant mashed potatoes. I blend sautéed onions and garlic with the mashed potatoes and sometimes put sliced fresh mushrooms on top with the cheeses.

I do remember some places in Buffalo, back in the early 70s doing "Polish Pizzas", which were essentially open-faced pierogis.
