Begin by rinsing the canned black beans and corn under cold water. This step reduces sodium content and improves taste. Let them drain well.

Using a sharp knife, dice the red bell pepper, cucumber, and red onion into bite-sized pieces for easy mixing and a good presentation.

In a large mixing bowl, combine the rinsed black beans, corn, diced bell pepper, chopped cucumber, and red onion. Gently mix everything with a rubber spatula.

In a separate small bowl, whisk together lime juice, olive oil, cumin, salt, and pepper to create the dressing.

Pour the dressing over the salad mixture, add chopped cilantro, and toss gently to ensure everything is coated in the dressing.

Taste the salad and adjust the seasoning as needed with lime juice or salt.
