How to Make It
Preheat oven to 375°.
Cut zucchini in half lengthwise; scoop out pulp, leaving a 1/4-inch-thick shell. Chop pulp. Place the zucchini halves, cut sides up, on a baking sheet lined with parchment paper; sprinkle with 1/4 teaspoon salt and 1/8 teaspoon black pepper. Bake at 375° for 15 minutes or until tender.
Heat a medium saucepan over medium heat. Add 1 tablespoon oil; swirl to coat. Add rice, cardamom, and cinnamon; cook for 5 minutes or until the rice is opaque, stirring frequently. Add 1/4 teaspoon salt, cumin, red pepper, and 1 1/4 cups water. Bring to a boil; cover, reduce heat, and simmer 12 minutes. Remove from heat; stir in apricots. Cover and let stand 10 minutes; discard cardamom and cinnamon. Spoon rice mixture into a large bowl; cool slightly.
Combine remaining 2 tablespoons olive oil, remaining 1/2 teaspoon salt, remaining 1/4 teaspoon black pepper, orange rind, and juices in a small bowl; stir with a whisk. Add dressing, reserved zucchini pulp, pistachios, and remaining ingredients to rice mixture; toss well to combine.
Preheat broiler to high.
Spoon about 1/4 cup rice mixture into each zucchini shell. Broil 6 minutes or until lightly browned.
