Heat the olive oil in a large pan over medium-high heat. Add the onion, garlic and cumin and cook for 1-2 minutes, stirring so the garlic doesn’t burn, just until the onions barely start to soften and everything is fragrant.
Add the black beans and tomato juice. Decrease heat to medium and continue to cook, stirring occasionally until everything is heated through. Add chopped cilantro and serve.
Cilantro Lime Rice
In a blender, combine all ingredients except rice and 1 tablespoon of the lime juice. Blend for 5 seconds, just to chop everything up so you don’t have any large chunks of onion or garlic, then pour into a medium size pot with the rice and give it a stir.
Place your pot over medium-high heat and bring to boiling, then cover and reduce heat to low. Simmer for 15 to 20 minutes, until the water is absorbed and the rice is tender. Add remaining tablespoon of lime juice and additional chopped cilantro and fluff with a fork before serving.
