Make the Dressing. In a small bowl, whisk together olive oil, lime juice, minced garlic, cumin, salt, and pepper until well combined.
Combine the Salad. In a large mixing bowl, combine black beans, corn, bell pepper, cherry tomatoes, and red onion. Pour the dressing over the top.
Toss and Garnish. Toss the salad gently to coat all the ingredients evenly with the dressing. Garnish with fresh cilantro.
Serve. Serve immediately or chill in the refrigerator for 30 minutes to allow the flavors to meld. Enjoy as a side dish, a topping for tacos, or a light meal.
