Heat a skillet to medium high heat and spray with non-stick cooking spray.
In a bowl, whisk together 2 eggs, egg yolk, milk, salt, and pepper. Then, pour eggs onto pan.
Scramble eggs with a spatula until cooked to desired consistency (I like mine well-done).
Next, separate scrambled eggs between your tortillas and top with black beans, salsa, and Tzatziki Sauce.
Feel free to add in any other toppings at this point! Some suggestions are: quinoa, brown rice, sauteed peppers and onions, corn, avocado, guacamole, etc.
