Now, start layering your “eggplant stack”. Start with an eggplant round, then add a slice of tomato, a drizzle of olive oil, salt, pepper and now grate about 1tbsp of parmesan on the top. Now add crumbled sausage. Repeat with another round of eggplant, tomato, herbs, olive oil, parm, etc. Top with a final (3rd) eggplant round and cover in grated cheese. Bake in a 350 degree oven for 10 minutes or until the parmesan has melted.
