Make ahead freezer meals for one

I live alone and am a teacher. I come home from school tired and starved as I go all day on granola bars, cheese and crackers and an apple. lol
Anyway, I get home and just want to eat something fast and it usually ends up being a ham sandwich or bowl or cereal! Does anyone have good recipes for meals I could make ahead, freeze and then reheat in the microwave? I like to cook and figure I could cook on the weekend a couple of times a month for a few meals to add to my menu of ham sandwiches and cereal!

Thanks!
