Saute the yellow bell pepper and onion in 1 tbsp olive oil in a large skillet until the vegetables are tender. Add the corn, and saute 4 minutes. Stir in the salt and pepper; remove from the heat, and set the yellow bell pepper mixture aside.
Bring the chicken broth to a boil in a large saucepan over medium heat. Stir in the remaining 2 tbsp olive oil, couscous, turmeric, and cumin. Remove from the heat, and cover. Let stand for 5 minutes or until the liquid is absorbed.
Gently stir in the reserved yellow bell pepper mixture.
Serve hot as a side, or at room temperature as a salad.
