Add the vegan sour cream, vegan cream cheese, taco seasoning, chili in adobo, and nutritional yeast to a blender. Blend until smooth and well combined.
Transfer the dip to a serving bowl and top with iceberg lettuce, vegan cheddar cheese, tomato, green chilis, and black olives.
Notes
To store: Transfer any remaining dip to an airtight container and refrigerate for up to 3 days. While the dip itself keeps well, the fresh toppings might lose their crispness over time.To freeze: You can freeze the taco dip base for up to 3 months in an airtight container or freezer bag, but I do not recommend freezing once the toppings are added, as they won’t freeze and thaw well.
