As hinted at by Thorpy, don't necessarily think of what you can quickly make at the time, also consider what freezes well. Bolognaise, curry, all things like that freeze really well - make a huge vat of it, freeze down, reheat one portion at a time! Result!
Noodles!
Bought a x2 packs of 24 from Costco, they're delicious. You can also add chicken and whatnot into them.
