For the pastry cups: Place an oven rack in the center of the oven. Preheat the oven to 400 degrees F. Spray a 24-count nonstick mini-muffin pan with vegetable oil cooking spray. Unroll the pie crusts on a lightly floured work surface. Using a 2 1/2-inch round cookie cutter, cut 12 circles of dough from each crust. Press the dough into the prepared muffin cups. Bake until light golden, 10 minutes. Cool completely before filling, 15 minutes.
For the salad: Bring the broth, orange zest, orange juice and cumin to a boil in a small saucepan over medium-high heat. Stir in the couscous and remove the pan from the heat. Cover the pan until the liquid had been absorbed and the couscous is tender, 5 to 6 minutes. Fluff the couscous and break up any lumps, using a fork. Toss together the couscous, mandarin oranges, almonds and parsley in a medium bowl. Season with salt and pepper.
For the dressing: Whisk together the oil, orange juice, vinegar, salt and pepper in a small bowl until smooth.
To assemble: Pour the dressing over the salad and toss until coated. Spoon the mixture into the cooled pastry cups and serve.
