**Prepare the Beans and Vegetables:**
Rinse and drain the beans if using canned. Chop the peppers, onion, and parsley. Add all the salad ingredients to a large mixing bowl.
**Make the Dressing:**
In a small bowl, whisk together the olive oil, red wine vinegar, lemon juice, garlic, Dijon mustard, honey, salt, and black pepper until emulsified.
**Combine the Salad:**
Pour the dressing over the bean and vegetable mixture. Toss gently to coat everything evenly.
**Chill and Serve:**
Let the salad sit in the refrigerator for 15–20 minutes to allow the flavors to meld before serving.
