Open a can of cannellini beans, drain and rinse them well. Place the beans, soy milk, nutritional yeast, lemon juice and spices into a blender jar. Blend until smooth, then adjust to taste preferences. For more cheesiness, increase the amount of nutritional yeast – and perhaps even add some garlic powder or freshly minced garlic, which takes this low-fat vegan cheese sauce to a whole new level.
