Pizza a Caballo, or Farinata with Pizza 

Pizza a caballo ("pizza on horseback"), or a slice of fainá on a slice of pizza. Fainá is the name for farinata in Argentina, where they eat this dish. I first made farinata, a baked chickpea flour pancake, recently, and wasn't sure if I got it right. When I Googled it, I learned about the combination. For the pizza, I used potato focaccia topped with some pizza sauce and toasted. No cheese, so this version is vegan.

Potato Focaccia from Southern Italy, 

From recipe by Anissa Helou in Savory Baking from the Mediteranean. I think the addition of mashed potato may be what causes the focaccia to rise so high. Delicious, and good for so many things, or just by itself.
