Juice of ½ - 1 lemon(about 1-2 tablespoons, to taste)
Prepare the couscous according to the package instructions. For extra flavor, substitute chicken or vegetable broth instead of the water + salt! When the couscous is cooked, rinse under cold water and place in a large bowl.
White the couscous is cooking: In a large skillet, heat 1 tablespoons olive oil. Season the shrimp with salt, pepper, and garlic powder. Saute the seasoned shrimp and diced bell pepper over high heat for about 5 minutes, or until the shrimp is fully cooked. Add to the large bowl of couscous.
To prepare the salad, add the grape tomatoes, corn, chopped parsley, and scallion to the couscous. Season with the remaining 1 tablespoon olive oil and juice of ½ lemon. Mix well and give it a taste. Season with additional lemon juice, olive oil, salt, and pepper, if desired. Serve at room temperature or chilled.
