This is one of our favourite summer dishes, when the zucchinis and eggplants are plentiful.
I like to throw the 1cm thick slices of zucchini and eggplants on the barbie until they are nicely browned and just cooked. This gives them a beautiful flavour.
Then assemble your lasagna as you would any meat-based one. We use home-made lasagne sheets, and they make quite a difference. The eggplants give the dish quite a 'meaty' texture. Yum! :)
