Creamy Ravioli & Pesto Gratin

Creamy Ravioli & Pesto Gratin via Real Simple

Real Simple's recipes using frozen cheese ravioli as the foundation are some of my favorites.  They're easy & inexpensive.  I think I'll add some leftover snap peas to this mixture before browning the top.  By the way, that's what a "gratin" (pronounced "GRAH-ten") is: something that's browned on the top, usually consisting of cheese & sometimes butter & breadcrumbs.  (Yes, please.)
