“These tacos are a beautiful way to serve black beans, which contain at least eight different flavonoids — phytonutrients with anti-oxidant properties. One caution, though: canned beans may contain high levels of sodium, which usually can be reduced by rinsing the beans in water. These black beans can’t be rinsed, of course, and in fact will be reduced. Avoid the temptation to add salt to this recipe.”
Advance preparation: The refried black beans will keep for three days in the refrigerator. You will have to moisten and thin them with water when reheating.
