Add the basil, nuts, garlic, lemon juice, nutritional yeast and sea salt to a food processor or blender and blend/mix on high until a loose paste forms.
Add veggie stock or water a little at a time (streaming in while the machine is running if possible) and scrape down sides as needed. Add more in tiny amounts to achieve the desired consistency.
Taste and adjust flavor as needed (more nutritional yeast for a “cheesy” taste, more lemon or garlic for pizzazz, etc. Experiment and make it your OWN!)
