Heat oil in 4-qt. saucepan over medium-high heat. Add sofrito, sazón, bouillon and oregano. Cook until vegetable mixture becomes soft and fragrant, 1 – 2 minutes. Add ½ cup water, beans and tomato sauce to vegetable mixture. Bring water to a boil; reduce heat to medium low and simmer, stirring occasionally, until flavors come together and bean mixture becomes thick, about 15 minutes. Season beans with adobo.
Divide rice evenly among serving plates. Serve seasoned beans on top or alongside rice.
