To marinate the meat, mix the meat cubes, melted butter, salt, paprika, and olive oil together and refrigerate for an hour.
Preheat the oven to 350˚F.
Grease the baking sheet with olive oil.
Lightly dust the work surface with flour. Place the dough here for rolling out to a rectangle that is a ¼ inch thick and 2 inches bigger than the size of your baking sheet.
Fold the dough edges in to create a thick 2-inch border all around.
Sprinkle the meat over the dough in a single layer.
Brush the border of the dough with some of the whisked egg and keep the rest for later.
Bake the pizza for 20 minutes before taking it out of the oven and pouring the remaining egg over the meat filling. Brush the border with a bit more olive oil.
Bake for a final 7-10 minutes to cook the egg. The crust should be golden-brown.
Let the cooked pizza cool on a wire rack before serving.
