Preheat oven to 425°.
Split pita rounds in half horizontally, forming pizza crust. Place pita halves, cut sides up, on an ungreased baking sheet; sprinkle with garlic.
Drizzle 1/2 teaspoon oil over each pita half; top evenly with artichokes and remaining ingredients.
Bake at 425° for 8 minutes or until cheese melts and edges are lightly browned.
