Breakfast is something I usually drink in the form of a smoothie, but I love to eat eggs when I have a few extra moments to cook or eat at home before starting my day. Packed full of protein and low in calories, eggs are the perfect way to keep you feeling full until lunch while gaining important vitamins and nutrients. My Feta and Spinach Egg White Omelette is a delicious way to start the day and hit your healthy eating goals, especially if you’re trying to cut calories!

Ingredients

  • Egg whites: While the egg yolk contains the majority of the nutrients, egg whites are almost entirely protein with no fat or carbs, making them very popular for those trying to lose weight or build muscle.
  • Olive oil: I most commonly cook with olive oil as it’s a heart healthy oil that is mild in flavor.
  • Red onion: Vibrant in color and flavor, it softens and sweetens as it cooks.
  • Sun-dried tomatoes: A bit chewy in texture, sun-dried tomatoes add a lovely tart, acidity to the omelette.
  • Spinach: I usually use baby spinach, as the leaves are smaller to begin with and it cooks down quickly. Spinach is full of nutrients like vitamin E and magnesium.
  • Feta cheese: A soft, crumbly cheese made from goat’s milk that is tangy and salty.

How to Make Feta and Spinach Egg White Omelette

Step 1. Start by dicing your red onion, mincing the sun-dried tomatoes, and washing your baby spinach.

Step 2. Next take your eggs and separate the yolk from the whites. My favorite way to do this is just passing the yolk back and forth between two halves of the shell letting the white fall into the bowl.

Liz’s Notes

To separate yolk from egg whites, carefully pour the yolk back and forth between the two shell halves, allowing the whites to slip out. Alternatively, hold the egg gently in your hand letting the whites slip through your fingers.
