Egg White Omelet with Spinach, Cheese and Avocado

Preheat a non-stick pan over medium heat. If you don't have one, add a little oil.

In the meantime, beat the whites in a bowl and salt and pepper to taste.

Once heated, add the egg whites and let cook for 3-4 minutes until set.

At the same time, chop the spinach, cut the cheese into strips and slice the avocado.

You can use any white cheese you prefer, such as feta, ricotta, mozzarella or cottage cheese.

Add the chopped spinach and the cheese cut into strips and place evenly. Cover for 2 minutes to let the cheese melt.

Use a spatula to fold the omelet in half.

Turn off, remove and serve with the avocado slices on top or on the side.
