Game Day Black Bean Dip

Heat oil in a skillet over medium heat. Add onion, jalapeno, and garlic. Cook until onion is soft and translucent, about 5 minutes, stirring often to prevent garlic from burning. Add cumin, chili powder, salt, and cayenne pepper and cook 5 minutes more. Remove from heat and let cool slightly.

Transfer onion mixture to a blender. Add black beans, reserved 1/4 cup liquid, lime juice, tomato paste, and vinegar and blend until smooth. Transfer to a serving bowl and garnish with cilantro.
