A simple and delicious make ahead lasagna, wonderful for entertaining. The process of degorging eggplant is an important step, ridding the vegetable of any unwanted bitterness. Degorging also removes excess water from the slices thereby requiring less oil in the cooking process. I find that dipping the no-boil sheets into the warm water, using an entire recipe of marinara sauce, and refrigerating the assembled lasagna overnight are key when using a no-boil lasagna.
