Heat the crepe pan on a high heat. Finely chop the onion into chunks, spray the frying pan 4-5 times with the oil and add the onions and cook for 1 minute.
Add the chorizo and allow to cook for a minute or two. While the chorizo is cooking beat the eggs in a bowl and add the chilli salt to the egg mixture.
Once the oil is starting to come out of the chorizo add the egg and swirl into around the pan to ensure a good and even coverage.
Cut the Leerdammer cheese into slices and lay on top of the omelette. If you have a blowtorch then use it to help melt the cheese.
After a few minutes slide the omelette onto a plate and enjoy.
