In a large skillet, heat oil over medium-high heat. Add shrimp and sear on both sides until slightly pink and almost cooked through (about 2-3 minutes). Add garlic and ginger and saute for 30 seconds, or until fragrant then add carrots and bell peppers and stir until slightly softened about 3 to 5 minutes. Add prepared noodles and sauce; toss and cook until hot and evenly mixed, about 2 minutes more.
