1) Put the pizza shell or focaccia onto a pizza pan or baking tray. Drizzle shell with oil and scatter minced garlic over shell to edges. Cover the pie with a layer of all 3 cheeses combined and work all the way to the edge of the shell.
2) Top with artichoke hearts. Cook 6 to 8 mins, until cheeses have melted and begin to bubble. Remove from oven and garnish with parsley. Cut pie with pizza wheel or knife into bite-size squares and serve.
