Before mixing your ingredients, get the steaming apparatus ready, bringing water to a full boil.
Have ready 4 square sheets of tin foil. In a large bowl, mash the beans until no whole ones are left. Throw all the other ingredients together in the order listed and mix with a fork. Divide dough into 4 even parts (an easy way to do this: split the dough in half and then into quarters).
Place one part of dough into tin foil and mold into about a 6-inch log. Wrap dough in tin foil, like a tootsie roll. Don’t worry too much about shaping it, it will snap into shape while it’s steaming because this recipe is awesome.
Place wrapped sausages in steamer and steam for 40 minutes, until firm. Remove from steamer and let cool completely before slicing. You’ll only need two of the pepperoni for this recipe
