As I said it’s easy. Take the ripe avocado and smash it. Add salt and pepper. Heat a frying pan and fry pita on both sides, both sides should be golden. Place pita on a plate, spread avocado, drizzle with lemon juice and olive oil, place freshly cut tomatoes on it and sprinkle with salt, pepper and chili flakes. Fry the egg and place it on top of your pita, put some chives on top. You can roll it, most probably it will be more comfortable version, or eat it like a pancake.
