Blend beans until very smooth. Mix in a tablespoon
or so of nutritional yeast if desired. Add salt and pepper
& garlic powder to taste. Stir in soymilk until
you reach desired 'cream of mushroom
soup" consistency.
I used this in a casserole that called for
cream of mushroom. This does not taste
exactly like cream of mushroom, but the
idea is that it will bind with other ingredients
to hold them together in a similar way.
Happy cooking!
