In a small bowl, whisk together lime juice, olive oil, apple cider vinegar, salt, and pepper to make the dressing.
In a large bowl, combine all sliced peppers, onion, jalapeño, green onion, and herbs.
Pour dressing over the vegetables and toss well to combine.
Let sit for at least 10 minutes before serving to allow flavors to meld.
Serve chilled or at room temperature.
Notes
• Make it ahead: Pepper slaw keeps well in the fridge for 2–3 days.
• Great topping for tacos, pulled pork, or grilled meats!
• Swap jalapeño for sweet mini peppers if you want it mild.
