To make the lasagna you will need at least 2 large zucchinis, sliced lengthwise into thin slices. The easiest way to do this is to use a mandolin, but a sharp knife will also work.
You can either make individual lasagna portions (like the ones pictured), or you can layer everything into a dish, as you would a regular lasagna.
Whatever you choose, start with a layer of the zucchini and then add a layer of the pesto. Top the pesto with another slice of zucchini and top it with marinara. Add another slice of zucchini and top it with cashew cheese. Add another slice of zucchini and then a layer of the walnut sausage.
Top with sprouts or micro greens and serve.
