Highly recommend!! Used regular spinach not baby, I think it has better flavor. Added 1 clove minced garlic and substituted plain fat free Greek Yogurt for the sour cream, in fact added a full cup instead of the half recommended. What a wonderful tangy flavor! (no need for lemon juice) I did get full 4 cups but if I hadn't, I saved some starchy cooking water from the pasta and would have added it to make the right amount. I had some leftover grilled chicken which added smoky flavor.
