Toss the shrimp with the lime juice in a bowl. Mix the garlic powder, onion powder, thyme, salt, red pepper and black pepper in a small bowl. Sprinkle over the shrimp and toss to coat well.
Spray a large skillet with non-stick cooking spray. Heat until hot. Add the shrimp and cook for 3 minutes, or until the shrimp are pink, stirring constantly. Spoon into a serving dish. Chill, covered, for 1 hour or longer. Garnish with lime wedges.
Makes 15 servings.
