Begin by preparing the ingredients: thinly slice half of a medium white onion and clean the button mushrooms by wiping them with a damp paper towel; slice the mushrooms into thin pieces.
In a medium non-stick skillet, heat 1 tablespoon of extra-virgin olive oil over medium heat.
Add the sliced onions to the skillet and sauté for about 5 minutes, stirring occasionally, until they begin to caramelize and turn golden brown.
Add the sliced mushrooms to the onions in the skillet. Sauté the onions and mushrooms together for another 5 minutes or until the mushrooms are tender and browned.
While the vegetables are cooking, crack the eggs into a bowl. Add 0.25 teaspoon of salt and 0.25 teaspoon of black pepper, then whisk the eggs until the yolks and whites are fully combined and slightly frothy.
Add the egg mixture to the pan, ensuring the vegetables are evenly distributed, and let it cook without stirring for about 1 minute until the edges begin to set.
Use a spatula to gently lift the edges of the omelet, allowing uncooked egg to flow underneath. Continue cooking until the eggs are just set, but not dry, approximately 2 minutes.
Once the edges are firm and the center is almost cooked, carefully fold the omelet in half using a spatula.
Slide the omelet onto a plate and sprinkle with chopped fresh parsley for garnish.
Serve the omelet immediately while warm.
