In a casserole dish, poured some pizza sauce (didn't have any tomatoe sauce). Placed the eggplant slices, then put a thin layer of spinach (I defrosted some frozen spinach, then wrung out so it wasn't soggy.) Add some more pizza sauce, then bread crumbs, then a thin layer of nutritional yeast. Somewhere along the way I also added some garlic salt, oregano. Put in oven and bake at 350 or 200ºC for about 20 minutes until warmed throughout. Turned out very tasty.
