In a sauté pan over low heat, melt the margarine. Add the garlic and cook for 2 to 3 minutes.
Transfer the margarine mixture to a blender or food processor, add the white beans and 1 cup of soy milk. Blend until completely smooth. If the sauce is too thick, add the remaining soy milk until you reach the desired consistency.
Pour the sauce back into the pan over low heat, then season with salt and pepper to taste. Add fresh herbs, such as parsley, if desired. Cook until the sauce is warm.
