Break the eggs into a jug and mix with the milk, tomatoes, a little bit of grated cheese, chilli flakes and seasoning

Melt the butter in a large pan and make it super hot! (but don't burn it!)

Pour the egg mixture into the pan and ensure the base is covered by swirling it around...

...then leave it alone for 15 seconds or so

Now start moving the mixture from the edges of the pan to the centre with a spatula, ensuring that you swirl the uncooked egg mixture into the space you have just created

Repeat until most of the egg mixture is cooked, being sure to be shaking the pan gently to stop it sticking

Add the rest of your cheese and all of your spinach to the top

After another 30 seconds or so carefully fold the omelette onto a plate so that the spinach and cheese are inside (with the cheese continuing to melt into/around the spinach)

Cut in half and serve with salad!
