My suggestions probably won't win you any wonderful wife awards!!

1) Dominos has a Monday meduim pizza deal for just $5!!
2) Lean Cuisine frozen dinners!  I really like the seasame chicken.  You need to have something on the side because it isn't much food.  How about an apple. :)
3) Cereal - works every time.
4) Hot Pockets!  - Have you caught on to my theme yet????

If you are prepareing meals ahead of time out of love then GO FOR IT!!  You are a wonderful woman.  If you are doing it out of necessity or obligation then FORGET IT!!  He's a big boy.  He won't die of starvation while you are gone.  :)
