This is a souped-up version of the recipe that sparked the idea for my recent book project. One night, a few years ago, my mom (Susan) called me up, asking for advice on what to do with the eggplant and tomato she had picked up from the local farm stand earlier that day. She was hoping to cook something low-fat and yet satisfying for her longtime companion, the original Mister Sausage, who was recovering from a recent heart attack.
