Heat pan over high heat.
Add oil.
Saute onion, ham, mushroom and green chilis.
Season lightly with salt and pepper.
Cook for about 3 minutes.
Transfer to a bowl and set aside.
Wash pan and heat again over high heat.
Or use another clean pan.
While pan is heating, prepare eggs.
Crack eggs in a large mixing bowl, add milk, parsley flakes and season with garlic salt and ground black pepper.
Beat well with a whisk.
When pan is really hot, add cooking oil
Pour ¼ of the egg mixture in the pan, swirl the pan to spread the scrambled egg
add ¼ of the ham filling in the center of the egg mixture in the pan
Using a spatula, lift the egg around the edges to make sure that it's not sticking, then fold the egg from one end to the other and then fold again like a burrito or fold cross-wise the second time to make a wedge.
Transfer to a plate.
Wipe pan with paper towel if there's some its sticking on it.
Then add oil again and repeat the process 3 more times to make four omelettes.
Serve immediately with a side of veggies and hot coffee.
Enjoy!
