Cut bell peppers in half lengthwise; discard seeds and membranes. Arrange halves in a 9-inch pie plate. Cover with heavy-duty plastic wrap. Microwave at HIGH 5 minutes or until crisp-tender; drain. Return peppers to pie plate.
Heat the oil in a large saucepan over medium heat. Add garlic; sauté 2 minutes.
Add the cumin, turmeric, and cinnamon, and sauté for 30 seconds. Stir in chickpeas and broth; bring to a boil. Stir in couscous; remove from heat.
Cover and let stand 5 minutes or until liquid is absorbed. Stir in 6 tablespoons cheese and 1 tablespoon mint.
Divide couscous mixture evenly among pepper halves. Top each pepper half with 1 1/2 teaspoons cheese, 3/4 teaspoon mint, and 1 1/2 teaspoons chutney.
