1/8 cup low-sodium, organic chicken broth (optional)
1 green onion, finely chopped
Cook pasta according to package directions; drain. Set aside.
While the pasta is cooking, combine peanut butter, soy sauce, vinegar, honey, and cayenne in small saucepan over medium heat; cook, stirring frequently, for 3 to 4 minutes, or until well blended and hot.
Add pasta to peanut butter mixture. If pasta is too dry, add chicken broth, a little at a time, to thin the sauce.
