In case you're wondering, the sauce I spent several days making turned out great. Each container is a generous ladle-full. I usually make my lunch right before I go to work and take it with me, so as long as I remember to defrost the sauce and leave enough time to boil pasta, I've got an easy meal all ready to go.
I keep a few things like frozen rice bowls and cans of soup handy for backup lunches. I don't think I've bought lunch in more than a month. And trust me, I do know all the lunch places around.
