Boil the egg and mix the mince with the spices
Put mince around the egg like u would with
Scotch egg make a onion masala as u wud for chicken masala
Add the kofta make sure the masala covers all the kofta then cook on low heat
So the kofta doesnt break

I have one recipe call nargis kofta but very long procedure from my mother in lows cook book(Her own recipe)published by her friend in 1965 will scan and post tomorrow if you are interested
