Colourful omelette
Method
Fry the potatoes, courgettes and peppers separately, season them with salt and pepper and leave them for a minute on a plate lined with kitchen paper to absorb the excess oil.
In a bowl, beat the eggs with the milk and Parmesan, adding a little salt and pepper.
In a wide non-stick frying pan, add the potatoes, courgettes and pepper and, over a low heat, pour in the egg mixture.
When the underside is cooked, carefully flip the omelette.
Serve hot, sprinkled with a soft melting cheese of your choice.
