How about instant or boil in bag rice? They have some microwavable flavored ones, too. Uncle Ben's makes some of those.
Or macaroni and cheese? Frozen or microwavable.
Stouffers makes frozen meatloaf and mashed potatoes, mac and cheese, and stuffed peppers, etc. Marie Callendars makes good frozen dinners, too.

Right now, I'm eating a lot of chocolate graham crackers, and am thinking about trying to put peanut butter on them. I eat a lot of instant rice, and have recently tried a new kind of Ramen called Yakisoba that I like a lot.
