Lightly spray one side of each of the bread slices with cooking spray. Turn the slices over and spoon 1 teaspoon of the salad dressing on each. Top four bread slices with a cheese slice and equal amounts of the tomato, basil, spinach, and olives. Top with the other four bread slices, salad dressing side down.
Heat a large nonstick skillet over medium heat until hot, and coat the skillet with cooking spray. Add the sandwiches and cook 1½ to 2 minutes or until lightly golden, turn, and reduce heat to medium low. (Add weight to the sandwiches by covering them with a sheet of foil and topping with a dinner plate and a couple of cans of soup or vegetables.) Cook 2 minutes or until browned on the bottom. Remove from heat and let stand, covered, 2 minutes.
