Well to start with, there's a spillion and one frozen meals that have "HEALTHY HEART", "EATING RIGHT", "LEAN CUISINE" and so on plastered all over the box, so you can start there. Still, eating frozen dinners all the time will kill you one way or another. You've already mentioned mastery of the "buy a 5 lb. bag of apples... and eat them!" method, so we'll skip that. And like I said, you can munch deli meats and cheeses right out of the ziploc, although you'll look like a lazy idiot doing it.
If you're eating out all the time there's always Subway. Yeah Jared's an annoying gimp but the calorie counts are sound - you can even go footlong and put everything on it and you'll have a huge balanced meal that's still not going to kill your weight too much. The only DO NOTs are mustard and mayonnaise which I personally hate anyway, and fancy shit like Philly Cheesesteak and Prime Rib subs.
Outside of that place you start to take your weight into your own hands though. Quizno's especially makes McDonald's look like Jenny Craig, if you can believe it.
Also what Rico said, but whatever, it's better than sitting there and eating chips I guess.
