If you're looking for a light, protein-packed breakfast that's quick and easy to make, this Mushroom, Onion, and Egg White Omelet is the perfect choice. With just a few ingredients and simple steps, you can whip up a delicious and nutritious meal to start your day off right.

Instructions:

1. Preparation: Begin by gathering all your ingredients. Slice the mushrooms and finely chop the onion.
2. Heat the Pan: Preheat a non-stick frying pan over medium heat. Once the pan is warm, spray it lightly with cooking spray oil.
3. Sauté Vegetables: Add the sliced mushrooms and the finely chopped onion to the pan. Stir occasionally and cook for about 3-5 minutes until the mushrooms are tender and the onions are translucent.
4. Season Vegetables: Add a dash of salt and a dash of black pepper to the vegetables in the pan. Stir to mix the seasoning well with the mushrooms and onions.
5. Prepare Egg Whites: While the vegetables are cooking, whisk the egg whites in a small bowl until frothy.
6. Add Egg Whites: Pour the whisked egg whites over the sautéed vegetables in the pan. Tilt the pan to ensure the egg whites spread evenly over the vegetables.
7. Cook the Omelet: Let the omelet cook undisturbed for about 2-3 minutes or until the egg whites are set. If needed, you can cover the pan with a lid to help the top set more quickly.
8. Fold and Serve: Once the eggs are set, use a spatula to carefully fold the omelet in half. Slide the omelet onto a plate and serve immediately.

Mushroom, onion and egg white omelet with black pepper and salt FAQ:

What pan size is best for making this omelet?

A 9-inch non-stick frying pan is ideal for this omelet. It allows enough space for the egg whites to spread evenly and ensures easy folding.

How do I know when the omelet is done cooking?

The omelet is done when the egg whites are fully set and no longer runny. It typically takes about 2-3 minutes of cooking undisturbed over medium heat.

Can I substitute whole eggs for egg whites in this recipe?

Yes, you can use whole eggs instead of egg whites. Keep in mind that using whole eggs will increase the fat and calorie content of the omelet.

How should I store leftovers from the omelet?

If you have leftovers, store them in an airtight container in the refrigerator for up to 2 days. Reheat gently in a microwave or skillet before serving.

What can I add to enhance the flavor of the omelet?

Consider adding herbs like spinach, bell peppers, or cheese for extra flavor. Just sauté them with the mushrooms and onions before adding the egg whites.

Tips:

- Prepare all your ingredients before you start cooking to ensure a smooth process.

- Keep the heat at medium to avoid burning the omelet.

- Use a non-stick pan for best results and easier flipping.

- If you prefer a fluffier omelet, you can whisk the egg whites a bit more to incorporate air into them.

- Feel free to add herbs like parsley or chives for extra flavor.
