Without meaning to brag, this is the best lasagne recipe I've ever tasted. It's perfect if you're trying to figure out what to do with ground venison because the tomato sauce does an incredible job of removing/masking the wild taste, but of course you can use ground beef as well. Even "Oh, I don't eat deer meat" people will love this -- just don't tell them until afterwards! My recipe book says the fennel is optional, but that's your KILLER SECRET INGREDIENT! It's not optional in my opinion!! You could also add a package of frozen spinach (thawed and drained) as well.
