A really good omelette filled with beef, fried mushrooms and grated mozzarella – just as welcome for breakfast, lunch or dinner.
This omelette is packed with flavour, it is properly filling, and it is very easy to make.
We used some leftover roast beef, which we fried off with onion and a few mushrooms – but you can use whatever leftover meat you happen to have; you don’t need very much.
