Step 1

Finely chop the spring onions and set aside. Thickly slice the potatoes (there is no need to peel them first), then boil in a pan of lightly salted water for 10 mins until just tender. Drain.

Step 2

Meanwhile snip the bacon into pieces with scissors. Heat a frying pan with 1 tsp oil, then stir-fry the bacon until it turns pink. Add the spring onions to the pan, stir briefly for a couple of secs to slightly soften, then tip the bacon and onion into a bowl. Wash and dry the frying pan.

Step 3

Break the eggs into a bowl, then whisk with the mustard and a little salt and pepper. Make sure you don’t get any shell into the mix. If you are worried you might, you can break the eggs into a cup, one at a time, before adding to the bowl – or ask an adult to break them for you.

Step 4

Grate the cheese and add half to the egg mixture with the cooked bacon, onions and potatoes. Gently stir to mix everything. Heat 2 tbsp oil in the pan; when it is hot, pour in the mixture, then stir a couple of times as it sets on the base of the pan to start it cooking.

Step 5

Turn on the grill so it has time to heat up. Leave the omelette to cook, undisturbed, over a low heat for about 6 mins. Meanwhile, cut the tomatoes into wedges, scatter over the omelette and sprinkle with the grated cheese.

Step 6

When the omelette seems set on the base, but is still a little eggy on top, put the frying pan under the grill to cook the last of the egg mixture and melt the cheese. Cool for 5 mins, then turn out of the pan. Cut into wedges and serve with ketchup, toast, tea and orange juice for a delicious family breakfast.
