Rinse the soaked black beans in a colander and set aside.

In a saucepan, heat olive oil over medium heat. Add chopped onion and sauté until translucent.

Add minced garlic and cumin, cooking for another minute until fragrant.

Add the rinsed black beans and water to the saucepan. Bring to a boil.

Reduce heat to low, cover, and simmer for about 30 minutes or until beans are tender.

Season with salt and black pepper to taste.

Serve hot, garnished with fresh cilantro.
