In a medium serving bowl, toss together the cucumbers, scallions and peppers.
Place the cilantro, lime juice, honey, salt and lime zest in the bowl of a food processor fitted with the metal blade and blend until smooth. Drizzle the mixture over the cucumbers. Toss to coat. Let the salad stand at room temperature for 30 minutes to blend the flavors. Just before serving, sprinkle with the peanuts.
