In large saucepan cook noodles in lightly salted water 3 minutes for Chinese noodles or 7 minutes for linguine; drain. Meanwhile, in small bowl combine ketchup, soy sauce, vinegar, and chili paste; set aside.
In wok or very large skillet heat oil over medium-high heat. Add red pepper strips, garlic, and ginger. Cook and stir 3 to 4 minutes or until pepper strips are crisp-tender. Add pea pods; cook and stir 1 minute. Add noodles and sauce mixture to wok. Toss to combine; heat through. Top each serving with lime zest and additional sliced pea pods. Serve with lime wedges.
