THE TOPPING: Heat the oil in a skillet over medium heat and add the garlic. Sauté briefly, then add the spinach and artichokes. Season with salt and cook until spinach is wilted. Season with pepper to taste.

TO ASSEMBLE: Preheat the oven to 500°F. If using dough, oil a heavy baking sheet and sprinkle lightly with semolina. Stretch the dough out thinly into a rectangle. (For naan, just lay each piece on a baking sheet.) Spread the spinach mixture over the dough, leaving about 1 inch around the edge. Cut the cheese into small bits and distribute evenly over the top. Bake for 15 to 20 minutes, until the edges of the crust are crisp and golden brown and the cheese is melted.
