For the dressing: Whisk the oil, vinegar, paprika, salt and pepper in a small bowl until smooth.
For the couscous: Heat the oil over medium-high heat in a large saucepan. Cook the couscous, stirring frequently, until golden, 4 to 5 minutes. Add 2 cups water and the salt and bring to a boil. Reduce the heat to medium-low. Cover and simmer until the couscous is just tender and the liquid is absorbed, 9 to 10 minutes. Set aside to cool slightly.
Mix together the spinach, tomatoes, cheese, peppers, parsley, almonds and mint in a large bowl. Add the couscous and the dressing. Toss until all the ingredients are coated. Transfer to a large serving bowl and serve.
