Slight oiling of Pan will let you increase the Working time without burning the egg and also proper and regular flipping of egg will allow you to have a good n all over cooked egg. Seeing you have added some fillings as well you need more oil accordingly othervise the egg burns coz all oil is soaked up and you end up with charcoaled egg. But making mistakes just means you are doing something new. While doing anything new, there are no failures just trials till you master it.
P.S. Tomorrow i will blog about a recipe called "Kufta" in Kashmiri made from minced meat. I hope you would love it provided you are non-veg.
