In a medium bowl, whisk together peanut butter, soy sauce, honey, rice vinegar, sesame oil, Sriracha, and minced garlic until smooth.

Taste the sauce and adjust the spice level with more Sriracha if needed, then set aside.

Slice cucumbers into rounds about ½-inch thick and place in a large mixing bowl.

Pour the spicy peanut sauce over the cucumbers and toss until well-coated.

Cover and refrigerate for at least 15 minutes to allow flavors to meld.

Garnish with chopped cilantro and peanuts before serving.
