Peel and roughly chop the yellow onion. Heat a glug of neutral oil in a medium saucepan and add the onions. Cook until tender and slightly browned.
Add the black beans, including their liquid, to the saucepan. (If using dry beans, soak them and cook them in their soaking liquid. Include this liquid as you would canned beans).
Season with salt, garlic powder and ground cumin. Cook until the beans have warmed through.
Add the black beans to a food processor and blend until smooth. Return the beans to the saucepan and set them to low heat. Break apart the goat cheese log into smaller pieces and fold into the black beans. Continue stirring to soften and completely incorporate the goat cheese.
Serve warm or room temp with tortilla chips or crudités.
