Put the beans, garlic, lemon juice, herbs and nutritional yeast in a food processor (best) or blender (will work ok) with about half a cup of water. Process/blend until smooth, adding water as necessary for the right consistency. For a dip, use less water; for a sauce, use more water. Once you have the consistency you want, add salt to your taste.

Use the sauce over chopped cauliflower, either raw or lightly steamed. To steam, put the cauliflower in a steaming basket over a small amount of boiling water for about 20 minutes.
