Any tips on subbing turkey (or another ground poultry) for the beef? I'm making this for Christmas dinner!

I haven't made this specific lasagna, but I often sub ground turkey for beef in lasagna, etc. (sometimes w/part ground pork too.) Works fine, no big adaptation necessary.

I think sexyChopx suggestion of turkey sausage (or part sausage, part ground turkey) would work great too.

I've made this so many times I know it by heart. My personal favorite is using spicy and/or sweet turkey sausage (removed from the casings) instead of the beef.
