These were so good!! Everyone liked them. A lot of fun to assemble. I added Sausage to the Ground Beef to give the meat more flavor. I also used Sharp Cheddar Cheese with the Mozzarella, added Spinach, Olives, Red Onion, and Shredded Carrots. I think when assembling a lasagna anything you would like to add usually works. Great also to put in the kids lunch the next day.
