How to make
Arrange the 9 bread slices in a square (3 by 3) in a tray covered with baking paper. Preheat the oven to 450°F (230 °C). Cut the 3 end slices into triangles like the tips of a crown.
Pour ketchup on the slices and place the ham on top. Cut the tomatoes into pieces and spread them over the entire pizza. Add the grated cheese.
Finally, sprinkle oregano, salt and pepper. Put the pizza in the oven and bake it for about 12-14 minutes.
