CHEESE OMLETTE IN A ROLL

Slice the tops off the rolls about a third of the way down to act as a lid; remove the bread from the insides of the rolls but not from the lids; use half of the butter to spread the insides of the rolls
In a bowl lightly beat the eggs with a fork and add the herbs, 4 tablespoons cold water and salt and pepper to taste
Put a knob of the remaining butter in a small non-stick frying pan, over a fairly high beat, let it start to foam, then add a quarter of the egg mixture and scatter over some of the cheese; let the omelette set briefly before tilting the pan to allow the liquid egg in the centre to flow to the edges and set; fold in half and carefully tip into one of the hollowed-out rolls
Make the rest of the omelette rolls in the same way, leaving to cool before putting the bread lids on; serve with a salad of your choice
