Eggs are one of the richest sources of vitamin B12. As per USDA, 100 grams of boiled eggs contain 1.1 micrograms of vitamin B12.
According to the estimation given by the USDA, egg in the hard boiled form carries more vitamin B12 than in any of its recipes. For example 100 grams of omelette contains 0.8 micrograms of vitamin B12.
Therefore, depending on the type of the food you take in the entire day, you can decide how you want to eat your egg.
To prepare egg omelette you need two eggs, some chopped vegetables (par boiled) to stuff your omelette, one scoop of butter, some salt and black pepper and other seasonings as per your choice.
Heat the pan. Take a flat pan, not a kadhai, so that it will be easy for you to turn your omelette while cooking. Add butter, wait till it melts. Add the vegetables; saute it for a while. Crack the eggs in a bowl and beat it properly with salt and black pepper. Pour the egg over the vegetables. Let it cook on one side and then turn it over. Cook both the sides properly and then add the seasonings.
