Crack the eggs into a bowl, add the salt and whisk (a fork works great) until well combined.
3 large eggs, ⅛ tsp fine sea salt
Preheat your skillet over medium-low heat. (For best results, use a non-stick or low-stick pan like a well-seasoned cast iron or properly preheated stainless steel.)Once the pan is hot, add the butter and swirl to coat the bottom evenly.
2 tsp butter
Pour in the eggs and cover the skillet with a lid (this helps cook the top without flipping).
½ avocado, ½ cup tomato, 1 tbsp green onion
While the eggs cook, prep your toppings (or have them sliced ahead of time for busy mornings).
After about 2 minutes, lay the sliced cheese over one half of the omelet. Cover again and cook for another 2-3 minutes until the eggs are just set and the cheese is melted.
Spoon about ¾ of the filling (avocado, tomato, and green onion) over the cheesy half.
Fold the omelet closed, transfer to a plate and top with the remaining filling. Enjoy!
Notes
Leftovers: This omelet is best enjoyed fresh, but if you do have leftovers, store the eggs and filling separately to maintain the best texture for up to two days. Reheat the eggs in the microwave or gently in a skillet then add the toppings/filling just before serving.Make Ahead: For easier mornings, you can prep the filling ingredients ahead of time and store them in an airtight container (up to 2-3 days ahead). You can also cook the omelet in advance (about 1-2 days) but wait to add the toppings until just before eating (and right after reheating) for the best flavor and texture.
