Melt butter in nonstick pan over medium heat. Add diced jalapeño and onion to pan and cook until onion is translucent, stirring occasionally (about 3-4 minutes).
Add garlic, cumin, and salt and continue stirring for about 1 minute, or until aromatic. Add beans and tomato juice, then stir together. Once well combined, place lid on and allow to cook on medium heat for about 6-7 minutes.
Turn heat to low, remove lid and let it simmer for about 3-4 minutes, stirring occasionally. This will allow excess liquid to cook out.
Garnish with cilantro and enjoy!
Notes
*Drain the excess liquid from the can, but it isn't necessary to get rid of all of it/rinse the beans off--the excess liquid is salty so leaving some in the recipe may add some flavor, but all of it is too much.
