I'd recommend you frozen-in-a-bag meals but I'm in Australia and I don't know if we have the same brands as you do over there. Generally anything from McCain or Continnental is really good, especially the stir-fry variety from McCain.

rice keeps very well in the freezer, you don't always have to mix it in with the casserole.

They're pretty easy to make, usually I just buy the powdered sauces, cut up the appropriate vegetables and meat, shove it all in a pan, and let it stay there until everything cooks, then place them in little containers for the freezer. Same with rice, except to save space I put those in freezer bags heh.
