Italian sausage with red grapes

ITALIAN SAUSAGE WITH RED GRAPES

2 tablespoons olive oil
2 lb sweet Italian sausage (about 12 3- to 4-inch links)
2 lb seedless red grapes, stemmed
1/4 cup balsamic vinegar
Accompaniment: sautéed greens with garlic

Heat olive oil in a 12-inch heavy skillet over moderate heat
until hot but not smoking, then cook sausages, turning over
once, until well browned, about 8 minutes total. Add grapes
and cook, stirring occasionally, until sausages are cooked
through and grapes are softened, 10 to 12 minutes. Stir in
vinegar and salt and pepper to taste.
