What's an easy, quick dinner i can make the night before & grab to go the following day?

i make ramen at work in a tupperware container then take it to night cl with me. it's still hot at the end of my 1 hour drive. just add hot water from the coffee machine, shake it up a little and it's cooked by the time you get there. to mix it up a little, i add frozen peas. i prefer beef over chicken.
