Is this a fattening menu for a day?

Yesterday for breakfast I had a banana, then a peach later on for a snack, a chicken ceasar salad (restaurant portion) for lunch and steamed salmon fillet for dinner. I am 16 years old girl, 5ft 6, 110 pounds. Is this a fattening menu for the day (especially the restaurant portion of chicken ceasar salad)? I have quite a sedentary lifestyle because for a summer job I am on the computer all day and finish work late
