Varies in piquancy. Will keep refrigerated for several months but should not be frozen. Available in 4-inch links at Latin American or Spanish groceries. Also available packed in lard in tins ranging in size from 5 ounces to 4½ pounds. Substitute any smoked, spiced, uncooked French, Italian or Polish sausage.
Wash the greens under cold running water. With a sharp knife, trim away any bruised or blemished spots and strip the leaves from their stems. Bunch the leaves together and with a knife cut them into strips about ¼ inch wide. Set aside.
Place the sausages in a small skillet and prick them in two or three places with the point of a knife. Add enough water to cover them completely and bring to a boil over high heat. Reduce the heat to low and simmer uncovered for 15 minutes. Drain the sausages on paper towels, slice them into ¼-inch-thick rounds and set aside.
In a heavy 6- to 8-quart casserole, warm the oil over moderate heat. Add the onions and garlic and, stirring frequently, cook for about 5 minutes until they are soft and translucent but not brown. Add the potatoes and stock and bring to a boil over high heat. Reduce the heat to low, cover the casserole partially and simmer for about 15 minutes, or until the potatoes are soft.
With a slotted spoon, transfer the potatoes to a bowl and mash them into a smooth purée with the back of a table fork, or purée them through a food mill or ricer into a bowl. Return the potatoes to the casserole, add the tomatoes and kidney beans, and stir until the ingredients are well mixed. Bring to a boil again, reduce the heat to low and simmer partially covered for 15 minutes.
Stir in the greens and simmer for 3 or 4 minutes longer. Then drop in the reserved sausages and cook for a minute or two to heat them through. Taste for seasoning and serve at once from heated soup plates. Serves 8.
