Wash the eggplant and cut into bite-sized pieces. Season with black pepper, olive oil, and chili sauce. Microwave on high for 1 minute 30 seconds (or just 1 minute if you prefer the eggplant less cooked). Remove and top with chopped cheese, then microwave for another 30 seconds. Take out and mix the eggplant and cheese together until well combined. (You can skip the cheese if you prefer a lower-calorie meal.)
