Most of the time, I take my lunch to work. I have a pretty good routine down and have pretty much "greened" my lunch bag to eliminate most of the one-time-use products. I have a Sigg water bottle. I use a fabric lunch bag. I put most food items in re-usable Tupperware or glass containers. The one thing that I was having a hard time with "greening" was sandwiches. I don;t have any Tupperware that is the right size and shape to accommodate a sandwich, so I was wrapping it in aluminum foil. Of course, I was recycling the foil, but still.
Then one day I was at the supermarket and I saw these sandwich wraps hanging in the bread isle.
Wrap-n-Mat and were I was intrigued! I bought one to try and ended up going back for another one. That way I can take a sandwich and pack one for Nate as well. I have found them really easy to use. As the name implies they are a mat that you wrap around a sandwich and then fasten with Velcro. All you have to do is wipe the inside clean after each use.
I am sure that there are lots of mamas on Hyena Cart and Etsy that make similar products, in fact I think my mom even bought one at a craft fair, but I couldn't beat the convenience of finding them in the supermarket.
