Heat 1 tablespoon olive oil in a medium skillet over medium heat.
Add 1/4 cup sofrito and sauté 3 to 4 minutes, stirring; if frozen, cover and cook on low until it melts, then uncover and sauté.
Add the can of black beans (15 oz, not rinsed or drained), 1/2 tablespoon sazon, 1/2 teaspoon chicken bouillon, 2 tablespoons tomato paste, and 1/2 cup water to the skillet; stir to combine.
Bring the mixture to a boil, then reduce heat, cover, and simmer 15 minutes to meld flavors and thicken.
Uncover and simmer 5 more minutes over medium heat, stirring occasionally, until desired thickness is reached; simmer longer to thicken or add water for soupier beans.
Taste and adjust salt as needed, then serve over cooked white rice if desired.
