Task: Question Answering
Input (English): My stomach woke me up this morning. It was rumbling so loud, at first I thought it was an earthquake! I jumped out of bed and ran to the kitchen. I knew that I was going to need something that would fill my empty stomach up, so I decided to make an omelette. I opened the fridge and grabbed a carton of eggs and some mixed vegetables I chopped up last night. Then I opened the cabinet to get a bowl to mix my eggs in. I scrambled the eggs up with a fork, and then got a pan to put on the stove to cook the eggs in. After I turned on the stove, I put some a little bit of oil in the pan so the eggs wouldn't stick. I hate when that happens, it always makes cleaning up after really hard! Then I poured the eggs from the bowl into the pan and waited for the eggs to start to firm up. I poked at them with a spatula, pushing parts from the edge of the pan that were kinda firm slowly towards the middle of the pan. The uncooked runny eggs slide over to where the firm eggs were and cook up really quick! When there was no more runny eggs left, I turned off the stove and spread my mixed veggies on one side of the omelette. Then I used my spatula to fold the omelette in half so that the mixed veggies were in between the sides of the omelette, kind of like a sandwich. I put my omelette on a plate and took it over to my table to sit down and eat. My stomach roared like a lion when I looked down at the omelette. I think it took me less than a minute to eat the whole thing! 
Question: What was added to the omelette?
Output (English): Chopped veggies.
