In a medium bowl, combine the artichokes, olives, ¼ cup cheese, lemon zest, mayonnaise and garlic; mix well.
Unroll the pizza dough and arrange it on a large baking stone (or greased cookie sheet), shaping it to fit on the stone/sheet. Using a lightly floured rolling pin, roll the dough to the edge of the baking stone. Spread the artichoke mixture evenly over the crust to within ½-inch of the edge. Arrange the tomato slices over the pizza; sprinkle with Italian seasoning and the remaining cheese.
Bake 20 to 25 minutes or until the cheese is melted and the crust is golden brown. Remove from the oven; let stand 10 minutes. Cut into squares using a pizza cutter; serve immediately.
