How to Make It
In a small skillet, melt 1/2 tablespoon of the butter over low heat. Add the pecans and sauté until lightly browned, 2 to 3 minutes. Transfer to a plate to cool.
Steam the broccoli until just tender, about 3 minutes. Drain well and toss with the remaining 3 tablespoons of butter and the salt. Mound the broccoli on plates or in bowls and sprinkle the pecans on top. Arrange a slice of prosciutto alongside and serve.
