1. Preheat oven to 350°.
2. Prick each eggplant several times with a fork. Place eggplant on a baking sheet, and bake at 350° for 20 minutes. Cool. Cut each eggplant in half lengthwise; scoop out pulp, leaving 1/4-inch-thick shells. Chop pulp; set shells and pulp aside.
3. Combine tomato and next 4 ingredients in a medium saucepan; bring to a boil, and stir in couscous. Cover, remove from heat, and let stand 5 minutes. Fluff with a fork; stir in eggplant pulp.
4. Spoon couscous mixture evenly into eggplant shells; place in a 13 x 9-inch baking dish coated with cooking spray. Top evenly with cheese. Cover and bake at 350° for 25 minutes or until thoroughly heated.
