Help me eat healthy!

Jasmine • 26. OB Nurse. Had my first baby October 2017! 💕 Now my husband and I are TTC another baby (our first together).
I live in my sorority house and we are required to have a meal plan at our house so I have no choice on anything I eat. Many of the meals are starchy and fatty and I've gained 15 lbs this school year alone because of this. Recently they have added a salad bar which is helpful but it doesn't have much variety. I would really love any suggestions you all might have! Besides just buying my own food, because I'm a poor college student.
