Lunch? It's in the bag!

Or, "Bag your frozen dinner and make lunch!" or "Brown bag is the new black!". So many cheesy titles, so little time.
Our Mom used to cut an apple in half, core it and put peanut butter where the core used to be, then stick it back together- that's always good. She also used to make the sandwiches on frozen bread so it would stay fresh and defrost by lunch, or freeze a juice box and use that as an ice pack.
Illustrator Kathleen makes homemade soup, then freezes it in small batches when she has a rehearsal after work. She then goes to any convenience store and uses their microwave to heat it up. The added benefits of the 7-11? "Free spoons and salt and pepper!" I guess you buy a slim jim if you're feeling guilty....
