Scrambled eggs with sausage, leeks and 'shrooms

To be honest, I'm not much of a scrambled eggs girl. I need 'stuff' in them. This week, 'stuff' meant leeks, mushrooms and sausage! The leeks are a mild alternative to onions with a sweet flavor.

4 eggs, beaten
1 chipolata sausage, cooked and sliced
1 handful button mushrooms, cleaned and sliced
1 leek, trimmed, rinsed and sliced
salt and pepper
small pat of butter

In a frying pan, melt butter over medium heat. Add mushrooms and leeks, cooking gently until softened. Add sausage, then eggs. Stir gently until just firm. Season with salt and pepper and serve hot.
