I don't know what a free Jarlsberg ToastaBag grilled cheese sleeve is, so take it away blockquote:
A ToastaBag is a handy bag to quickly make a grilled cheese sandwich in your toaster. Also make it cleanly, because no melted cheese or crumbs are left behind. Prepare your sandwich, put it into the ToastaBag and place it in the toaster or toast oven. It only takes 3 minutes to make a delicious toasted sandwich.
As someone who can't cook, I approve of this device. You have to submit your favorite grilled cheese recipe when signing up, but that shouldn't be too hard to fabricate if you don't have one. Although who doesn't have a favorite grilled cheese? I'd argue they're more American than apple pie at this point.
I also love this part of the fine print: “This offer may not be published in any magazine or website without Norseland, Inc's written permission.” Oh, silly companies that don't understand how the Internet works. You guys are hilarious.
