Put potatoes, onions, and cabbage in a roomy pot (the vegetables should
take less than 1/2 the depth of the pot). Add water to barely cover.
Bring to a boil; reduce heat, cover, and simmer until the potatoes are done
(a fork pierces easily)--about 20 minutes.
Split frankfurters lengthwise then cut each half into quarters. Heat the
oil in a heavy skillet; add frankfurters and cook until nicely browned.
Drain the vegetables and return to the pot. Add the milk and the browned
frankfurters and heat to serving temperature. Add salt and pepper to
individual taste. Serve with cornbread, biscuits, or hot buns.
