Drain and rinse the chick peas. In a bowl, combine the chick peas with the salt, crushed red pepper, olive oil, and half of the lemon juice. Stir, and let sit for 30 minutes or up to 4 hours. The longer the better!
When the chick peas have marinated, combine the parsley, tomato, cucumber, and couscous in a large bowl with the rest of the lemon juice. Sprinkle with salt.
Drain the chick peas and reserve the marinating liquid. Add half the chick peas to the tabouli mixture.
Stir gently together and taste the salad; drizzle over the marinade from the chick peas a little bit at a time until the salad is very flavorful. Sprinkle on extra salt and crushed red pepper to your taste.
Serve the salad in shallow bowls or plates topped with the remaining garbanzo beans. Enjoy!
