Saw this picture and recipe on Skinny Taste and couldn't resist. I used Asparagus and Gruyere Ravioli instead of spaghetti and ground sage instead of fresh. It was delicious! Skinny Taste is a wonderful website full of easy to prepare recipes with lots of pictures, my personal requirement. I would post a picture of my dish, but we scarfed it down before I thought to take a picture. Here's the link.
