There are many different types of oil that can be used for scrambled eggs. The type of oil you use is up to you and will depend on your personal preferences. Some people prefer to use olive oil, while others prefer vegetable or canola oil. You could also use butter, although this will give the eggs a richer flavor.
If you are using olive oil, make sure it is a good quality extra virgin olive oil. Heat the pan over medium heat and add the oil. Allow it to heat for a minute before adding the eggs. If you are using butter, melt it in the pan before adding the eggs.
Whisk the eggs in a bowl before adding them to the pan. Add them to the pan and scramble until they are cooked to your liking. Season with salt and pepper to taste. Serve immediately with toast or other accompaniments of your choice.
