In medium bowl, whisk 5 eggs, water, salt and black pepper. Cut reserved baked potato into small cubes (including skin); add to egg mixture, along with shredded extra-old cheddar cheese, green onions and olives. Preheat broiler to high.
Heat butter in large non-stick skillet over medium heat (if skillet’s handle isn’t oven-proof, wrap it in double layer of foil); tilt skillet to coat bottom and sides with butter. Add egg mixture, spreading potatoes to distribute evenly.Cook for 3 to 5 minutes, until eggs are just set on bottom.
Transfer skillet to lower rack of oven; broil for about 5 minutes until top is set. Cut frittata into wedges; serve at once.
