Sautéed Baby Greens and Prosciutto

Arrange the prosciutto on 4 plates. In a large skillet, heat 1 tablespoon of the oil until shimmering. Add the greens and a generous pinch each of salt and pepper and cook over moderate heat, tossing, until barely wilted, about 1 minute. Add the lemon juice and toss, then mound the greens alongside the prosciutto. Drizzle with the remaining 1 tablespoon of oil, season with pepper and serve.
