Cooking while in nursing school?

Hi! I’m in my last semester of nursing school. I’m also a single mother. I need some tips on dinners I can make my child and I with my busy schedule? I have studying, commuting us both to and from school, and preceptorship! By the way, my preceptorship is night shift. With this being said, I’m the busiest I’ve ever been before in my life! I really despise eating fast food every night, and I just need some ideas.
