Prepare the fries and the burger according to instructions on box. Pre-heat oven to 400 degrees. Crumble burger in a frying pan over medium heat. Add mushroom soup, peas and carrots and black pepper. Stir frequently until hot. Remove from heat. In an 8 X 8 baking dish spread the eggplant burger mixture evenly so it covers the entire bottom of the dish. Top with the fries and sprinkle generously with cheddar cheese. Place in the oven for about ten minutes, or until the cheese is melted. Serve hot.
