Tonight I'm making Easy Pesto Spaghetti. Pesto is an aromatic herb paste that has its origins in Italy, where people have been making it for hundreds of years with the brilliant green basil that grows wild on the hillsides. I found a super easy recipe online. It's not exactly traditional since it doesn't use Parmesan cheese or pine nuts but, you could certainly add those ingredients if you wanted.
