Baingan Bharta (Indian Baked Mashed Eggplant with Tomato)

The other day, I bought 3 large eggplants at the store. The next day, I baked all 3 until soft. One went into this dish. It is based on 2 baingan bharta recipes in Neelam Batra's The Indian Vegetarian. Good with any kind of bread, toast, or crackers. Never tried it with tortilla chips, but might also be good with that.
