In a small fry pan or skillet, add a spray of cooking oil and crumble over the feta cheese, ensuring the outside circle of the pan is also covered.

Allow the feta cheese to sizzle and sauté over a medium heat for a couple of minutes so the cheese can melt without burning. Gently crack the egg in the center of the pan.

Season the egg with a sprinkle of dried oregano and red pepper flakes and allow the egg to cook to your liking (whether that's medium or with a runny yolk).

Warm the tortilla on a gas stove, oven or in the microwave. Smash the avocado on top of the tortilla and add a squeeze of lemon juice.

When the egg is cooked and the cheese has created a golden brown crust, gently remove from the pan using a spatula and place on the tortilla.

Garnish with pickled onions, a drizzle of chili oil and enjoy your Crispy Feta Fried Eggs!
