Combine base: add snap peas and edamame to a large bowl.
Make dressing: whisk chili crisp, sesame oil, rice vinegar, soy sauce, honey, garlic powder, lime zest, and lime juice. Taste and adjust heat and seasoning.
Dress: pour dressing over snap peas and edamame. Toss to coat evenly.
Add toppings: add scallions, cilantro, and sesame seeds. Toss lightly. Adjust salt and pepper.
Serve: transfer to a serving bowl. Scatter peanuts and extra chili crisp if using. Serve immediately or refrigerate up to 2 hours.
