This recipe takes advantage of another wonderful summer crop – eggplant. I grew up with eggplant parmesan, and we would enjoy the leftovers as the filling for fantastic sandwiches made with crusty Italian bread. My family recipe included breaded and sauteed eggplant, which adds more richness, calories, and work. I have adopted a lighter version of this dish, which relies on oven-roasted eggplant slices. My recipe has a breadcrumb topping and a vegetarian tomato sauce. You can omit the bread crumb topping and have a gluten-free offering, and either way – it is a substantial and delicious vegetarian dish to delight friends and family.
Note: You can use a jarred marinara sauce to save a step. If you make the tomato sauce, the recipe is enough for at least two casseroles of eggplant. You want a good balance of all the ingredients, not too much of anything, and not too little. You can adjust the ingredients to your preference after making this casserole a few times.
