Bring a large pot of salted water to a boil over medium-high heat. Add the pasta and cook according to package directions. Drain, reserving 1 cup of pasta water.
In a large bowl, whisk together the peanut butter, soy sauce, honey, rice vinegar, lime juice, garlic, hot sauce, sesame oil, and ¼ cup pasta water. Add the noodles, tossing to combine. Add more pasta water, 2 tablespoons at a time, until a smooth sauce forms. Toss in the slaw mix, edamame, and green onion.
Serve warm or chilled, topped with more green onion and chopped roasted peanuts.
