It is tough to go against the flow. I know that fastfood isn't the healthiest, but maybe you should try to work with it. Most places have something that is acceptable, if not ideal. Maybe you should do some research on the resturaunt that you & the BF frequent, and figure out what is the best thing to eat there. Then when you are too tired to make something from scratch, you'll already know what you should have.
Oh, and welcome to 3FC!
