To make focaccia, prepare pizza-crust mix according to package directions. Coat an 8x1-1/2-inch round baking pan with nonstick spray. Pat dough into the pan. Cover; let rise in a warm place for 40 minutes. Brush with oil. Sprinkle with olives, lightly pressing into the dough. Sprinkle with 1 tablespoon cheese. Bake in a 400 degree F oven for 20 minutes or until golden. Cool on wire rack.
Cut focaccia into four wedges; split each wedge horizontally. Arrange pepper strips on bottom pieces of focaccia; top with the tomato and basil. Drizzle with dressing and sprinkle with remaining cheese. Top with remaining focaccia pieces. Makes 4 servings.
