Combine the couscous with the raisins, olive oil, salt, and paprika in a medium bowl. Add boiling water to it, about twice the volume of the couscous. Cover the bowl and leave to cook, around 5 minutes. When the couscous is cooked, it should have absorbed all the water. Fluff lightly with a fork to separate the grains.
In a separate salad bowl, combine the onion slices, chopped tomato, cucumber, olives, pomegranate, parsley, and mint with the juice of 1 lemon. Mix well.
Add the cooked couscous to the salad bowl and toss. Sprinkle the toasted pistachios, and adjust the seasoning according to preference. Serve at room temperature or slightly chilled!
