How do you eat enough food to get 2,000 calories per day?

I wonder how people are able to fit in 2,000 calories it is such a struggle for me even getting just over 1,000. I don't know what people eat?

I have soup veggie for breakfast, lunch, and dinner. Or chicken with mashed potato. Banana and peanut butter for snack. And I drink whey protein shake which makes up most of my calories. Also trying to eat healthy. Still don't know how you fit in so much food.

I am 5'2 and ~106 lbs aiming for 115 lbs. I have been weight lifting.
