Drain and rinse beans thoroughly to remove canned flavor and extra sodium. Chop all vegetables evenly so each bite has a balanced mix of textures. Keep pieces small enough for easy scooping with chips.
In a small bowl, whisk olive oil, vinegar, lime juice, honey, and spices until smooth. Taste and adjust salt or sweetness as needed. A balanced dressing ties all ingredients together.
Add beans, corn, tomatoes, peppers, onion, and cilantro to a large bowl. Pour dressing over and gently mix until evenly coated. Avoid overmixing so vegetables stay crisp.
Cover and refrigerate for at least 30 minutes before serving. Chilling allows flavors to meld beautifully. Add diced avocado right before serving to keep it fresh and vibrant.
Give the mixture a final stir and taste before serving. Adjust seasoning or lime juice if needed. Serve with tortilla chips or as a topping for tacos or grilled meats.
