Are you using and tossing bags every day? What a waste. Instead, get yourself a reusable container from Rubbermaid or Tupperware. It’ll hold your sandwiches (or your salads) for darn-near-ever, and you’ll throw far fewer bits of plastic into the landfill. No reason in the world to buy and toss lunch bags, either. Either purchase a lunchbox or tote your PBJs in whatever bag you have around the house.
