Lasagna rolls cooking time

I tried these out last night and Scott, Jeffrey and I really like them! (It's hard to please the twins right now, they are a little picky.) I wanted to let everyone know that after cooking it for 45 minutes at 350 degrees, it was still cold in the middle. I have actually had this problem before using the foil pans. Just plan on having time to cook it longer and check to see when it is done. I ended up having to pull it out and then I just heated mine and Scott's in the microwave for a little bit because we were ready to eat. We really enjoyed it and we still have some for leftovers! Thanks Aften!
