Put beans in a food processor or blender and add garlic, tahini, water, lemon juice, tamari soy sauce, cumin, coriander and a pinch of cayenne (you may add more later to increase the heat), and process until creamy and smooth.
Add avocado oil.
Puree again for about 15-30 seconds.
If necessary, add a little water to allow the mixture to puree a little easier.
