Task: Question Answering
Input (English): Omelettes make a great breakfast, and I enjoy making them because they are very easy to cook. First, I get the eggs out and begin cracking them on the side of the bowl and dumping them into the bowl. I normally use two eggs whites and one whole egg to cut the calories. I begin beating the eggs with a fork or a whisk. I add some salt and pepper to the mix for flavor. I pour the mixture into the hot frying pan. I make sure that I add some vegetable oil to the pan before I add the eggs though because I don't want them to stick. I let the pan sit for a bit so the egg mixture heats up a bit on one side. As this occurs, I add some cheese or vegetable to the center of the egg mixture. Really, almost any type of cheese or vegetable makes a good omelette. I then flip one side of the omelette over on to itself to seal in the contents in the middle. I then flip the omelette over several more times to lightly brown it on both sides. It is then ready to serve! 
Question: When did they put the eggs in the pan?
Output (English): After the eggs have been mixed with a fork or a whisk.
