Please do not alert the food police. Lunches around here are much more about convenience than about nutrition. There, I said it. I DO care that we eat well - I promise we don't have m&m's and cheetos for lunch too many days in a row. ;) (Because if you knew me, you'd know that I would not like for powdered cheese and m&m shell colors to get on our school papers!)
Seriously though - lunches around here are EASY. The youngest is usually out of the house during the day, so most days, it's just the girls and me. We have leftovers when they are available, or sandwiches, soup, or something frozen when there aren't leftovers. Occasionally I "cook" and we have quesadillas. Sometimes if the oldest finishes her morning work early, she'll be in charge of lunch. Those are nice days. ;)
Generally as soon as we finish lunch, we're rushing to get the classes that the girls do together done, so I'm not a big fan of lunches that require much clean-up effort. The question is specifically how do you break out of the soup and sandwich rut. Well, we don't. We have better and more complete meals for supper, but lunch? Easy and convenient. Period.
So, if you're keeping track, lunches must be easy, convenient, and non-messy. LOL
