A bright, punchy bean salad with fresh lime dressing that’s perfect for potlucks and picnics. It’s quick to make, packed with texture, and gets better as it sits.
For best flavor, let the salad rest in the fridge for at least 1 hour. Add avocado just before serving to prevent browning. If you prefer a milder onion flavor, soak the diced red onion in cold water for 5 minutes. To toast the cumin, heat it in a dry skillet over medium heat for about 30 seconds until fragrant.
