Dice the red onion, tomatoes, cucumbers, red bell pepper, and celery into small bite-sized pieces, and place everything into your large salad bowl. Toss to combine gently.
Next, add the drained and rinsed pinto beans, and toss again gently.
Drizzle the dressing onto the salad and toss gently making sure all of the dressing is spread evenly.
Season further with salt and pepper according to taste.
Cover and set in the fridge for a minimum of 30 minutes, on up to 1 hour. Allowing all of the flavors to blend together.
Serve pinto bean salad into beautiful bowls, sprinkle with additional parsley and/or cilantro, and serve.
ENJOY!
