What if you smoked the key ingredients, and then built it? You could spread out a layer of hamburger and/or sausage, maybe 1/2" thick, add some garlic and onions to the shelf (you'll need a seafood shelf), then smoke them for awhile (maybe an hour or two at a low temp). Then, build the lasagna and add some separately cold-smoked mozzarella and/or provolone cheese, then bake in the oven? Just a thought...
