Peel the eggplant and slice into 1/2" slices. Lay the slices onto a baking sheet and sprinkle with salt. Allow to sit for 45-60 mins. and then pat dry.
Place a couple of tablespoons of the sauce in a 2-quart casserole and spread around to cover the bottom. Place a layer of the eggplant into the casserole and top with some of the sauce and some of the cheese. (Be sure to reserve a bit of extra cheese for the top layer.) Continue layering until you have used all of the ingredients.
