Start by draining and rinsing your beans thoroughly in a colander until the water runs clear, removing excess salt and starch. Transfer them to a large mixing bowl.
Add the diced tomatoes, chopped cucumbers, and red onion to the bowl with the beans. Gently toss everything together with a spoon to combine the colorful vegetables evenly.
In a small jar or bowl, whisk together the minced garlic, olive oil, lemon juice, salt, and pepper until the dressing is smooth and slightly fragrant. This will create a bright, herby vinaigrette.
Pour the dressing over the bean and vegetable mixture, then gently fold with a spoon to coat everything evenly. The salad should look vibrant and slightly glossy.
Sprinkle the chopped fresh herbs over the top, adding a burst of aroma and color. Toss again gently to distribute the herbs throughout.
Taste the salad and adjust the seasoning with additional lemon juice, salt, or pepper as desired. Let it sit for about 10 minutes to allow flavors to meld.
Serve the salad at room temperature or chilled, enjoying the fresh, lively flavors with each bite. It’s perfect as a light main or a vibrant side.
