To make peanut dressing, combine peanut butter, teriyaki sauce, garlic, ginger, sesame oil, ground red pepper and water in bowl. Reserve 3/4 cup.
Alternately thread onto 8 metal skewers pork (about 5 pieces per skewer), peppers and onion. Brush with reserved peanut dressing. Broil kabobs 8 to 10 minutes, turning halfway through cooking.
In a large bowl, toss remaining peanut dressing with pasta. Top pasta with skewers and serve.
