vegetarian lasagna with butternut squash marinara

i don't have a photo of this one. we had friends over and it was devoured! thats the rewarding part of having people outside the fam eating over...watching them have seconds and loving it!
i had a couple cups of leftover butternut squash puree. i usually add pumpkin to my tomato sauce but needed to use this up. it was a really sweet and hearty addition to the marinara sauce. i also made a bechamel to thicken things up a bit. it was tasty and full of veggies and cheese! hopefully i can salvage a slice today to post a pic of it.

enjoy!
