Directions

1. Preheat oven to 400 degrees. Heat oil in a large skillet over medium-high heat. Add onion, garlic, 1/2 teaspoon salt, and 1/8 teaspoon pepper; cook until softened, about 3 minutes.
2. Add sausage to skillet. Cook, breaking it up with a spoon, until lightly browned, about 4 minutes. Add tomatoes and 1 cup water; cook until sauce is slightly thickened, about 5 minutes. Remove from heat, and stir in couscous.
3. Fill pepper halves with couscous mixture. Pour 1/2 cup water into a large baking dish; arrange stuffed peppers in dish. Cover with foil, and bake until peppers are tender, 35 to 40 minutes. Remove foil, and sprinkle Monterey Jack over the tops. Return to oven; bake, uncovered, until cheese has melted and peppers are very tender, 10 to 15 minutes.
