In a skillet over medium heat, add olive oil and sauté the chopped onion until translucent.

Add minced garlic and cook for an additional minute until fragrant.

Stir in the cooked beans, cumin, salt, and pepper. Mash the beans with a potato masher while adding vegetable broth until desired consistency is reached.

Cook for about 10-15 minutes, stirring occasionally, until heated through and flavors meld.
