This is not a paid product placement, just wanted to mention a product I tried and liked. I've never made ravioli, and not sure I've even ordered it in a restaurant, but this was very good. All natural, stays fresh in the bag. Cooks in 3 minutes in boiling water. http://www.giovannirana.com/products/mushroom-ravioli/
Last night I served it plain, from the pot, and it was excellent. Today I served it with some tomato based sauce.
There are a number of products—check product on the web site.
