Baked Ziti Neely Style

I was watching Down Home with the Neely's the other night and saw this recipe on their show and decided to try it.  Baked Ziti with Hot Italian Sausage and Spinach.  Yum.  And it was yum.  BUT, next time, I would mix in the spinach, ricotta, etc. in with the noodles instead of leaving it on top.  I think it would add more moisture to the spinach.  Either way, it is worth a try.  And it could be considered weeknight inspiration - it was easy but just required a lot of dishes which was a pain with no dishwasher...
