Preheat your oven to low broil. This is essential for achieving that golden, crispy taco shell. You want it just hot enough to heat through without burning.
In a frying pan, add 1 tablespoon of butter over medium heat. Let it melt completely, coating the bottom of the pan. The butter will add a rich flavor to the egg whites as they cook.
While the butter is melting, carefully separate the egg whites from the yolks. Discard the yolks or save them for another recipe. Use a whisk to lightly whisk the egg whites, incorporating air to make them fluffy.
Once the butter is melted, pour the whisked egg whites into the frying pan. Stir gently with a spatula, scrambling them. Keep an eye on the color and consistency; you want them just set, not dry.
While the egg whites are cooking, place the taco shells under the broiler for about one minute. Watch them closely, as they should be golden and crispy without burning.
When the egg whites are cooked to your liking, remove the frying pan from heat. The texture should be soft and fluffy, and they should look slightly moist but not runny.
Carefully divide the scrambled egg whites among the three taco shells. Use a spoon to scoop them in, making sure each taco is generously filled.
Now, it’s time to add your toppings! Sprinkle shredded cheddar cheese over the egg whites first, so it melts slightly from the heat.
Add salsa and guacamole on top of the cheese, followed by diced tomatoes, sliced olives, and minced cilantro. Each ingredient adds its unique flavor and texture, creating a delightful bite.
Serve immediately while still warm. Enjoy your Egg White Tacos with a smile, knowing you’ve made a healthy and delicious breakfast!
