You can make fluffy omelets in less time (and with much less effort) than you may think. This Mediterranean-inspired version has a filling of grape tomatoes, scallions, oregano, and feta cheese.
In a small skillet over medium heat, warm olive oil. Cook grape tomatoes, scallions, and oregano until tomatoes have softened, about 1 minute. Remove from heat; add feta cheese and olives.
In a small bowl, whisk together eggs and salt until frothy.
Make omelet, adding 1 teaspoon olive oil or butter to heated pan; fill with tomato mixture.
