Lightly coat a frying pan with oil and scramble the three eggs, seasoning them with salt and pepper. Just before they look done, top the eggs with the feta cheese and remove the skillet from the heat. (Eggs will continue to cook in the hot skillet).
Warm two flour tortillas in the oven on low or in the microwave for 20 seconds.
Divide eggs in half and place into tortillas. Top with tomatoes and avocado and sprinkle with a bit more sea salt and pepper.
Use whatever toppings you have on hand - salsa, cheese, bacon, etc.
