Heat oil in a pan and once hot add chopped onion. Cook over medium heat for about 5 minutes, stirring frequently, then add a splash of water or vegetable broth. Keep cooking the onion for about 20 more minutes, adding more liquid if needed, until the onions are nicely caramelized.
To a medium bowl, add vegan sour cream, caramelized onions, and all other ingredients. Stir to combine.
Taste it and adjust seasonings. You can also add a pinch of cayenne pepper for some heat. Garnish with fresh parsley and enjoy!
