Stir the garlic into the tapenade. Cut the dough rounds into 4 pieces (1 1/2-ounce pieces) and roll those out to 1/8-inch (if possible, roll out to desired thickness by using a pasta machine). Cover the top of the rolled out dough with olive paste and garlic mixture. Drizzle each pizzetta with olive oil. Sprinkle the thyme and salt and pepper on top. Lay the pecorino on top of pizzetta.
Place the pizzettas onto a lightly floured baking sheet. Bake them for 15 minutes or until light brown (a cracker like thinness and texture). Let cool for about 10 minutes, and serve.
