Preheat broiler. In an 8-inch broiler-proof nonstick skillet, cook sweet pepper and onion in hot oil over medium heat for 5 minutes or just until tender, stirring occasionally. Meanwhile, in a medium bowl combine eggs, half of the cheese, the parsley, oregano and black pepper.
Pour egg mixture over the pepper mixture in skillet. Stir in olives. Cook over medium heat. As mixture sets, run a spatula around the edge of the skillet, lifting egg mixture so uncooked portion flows underneath. Continue cooking and lifting edges until egg mixture is almost set (surface will be moist). Arrange tomato slices on top of egg mixture. Sprinkle with remaining cheese.
Broil 4 to 5 inches from the heat for 2 to 3 minutes or until center is set. Let stand for 5 minutes before serving. Cut into four wedges to serve. Serve with baguette slices.
