In our house, pesto has as many, if not more, uses then tomato sauce. I've started to keep pesto in the fridge at all times because of it's versatility and the fact that my kids love it. Not only is it great as a sauce for pasta, it's also a great spread for sandwiches, like these cheesy bagel paninis. It's sort of like a grilled cheese, updated with a little extra zip.
When I'm short on time, but still want a school lunch with tons of flavor, these cheesy bagel paninis are a sure fire hit with my gang!
