I eat at a lot of fast food places too (socially acceptable thing to do at my work...) and here are my tips FWIW:
SALADS! Jack in the Box has a great chicken club salad served with Almond Accents instead of croutons. Wendy's chicken BLT salad has a good amount of LC ingredients, too.
Carl's Jr.'s $6 Burger is pretty meaty and they will serve it with no ketchup and on a plate sans bun. Otherwise, if I want a burger (or two) I just take the bun off myself.
Boston Market is a good choice
Baja Fresh has a fajita plate

Anyway, good luck!
