Olive slivers add a tangy note to steamed broccoli florets.
Prepare an ice-water bath; set aside. Put broccoli in a steamer basket over boiling water, cover, and steam until just tender, about 7 minutes. Briefly plunge into ice-water bath. Drain; pat dry.
Heat 1/4 cup oil in a wide saute pan over medium heat. Add half of the broccoli, 1/2 teaspoon salt, and 1/4 teaspoon pepper; cook, stirring, until golden brown, about 5 minutes. Stir in half of the olives. Cook until heated through. Transfer to a serving dish; cover. Repeat with remaining oil, broccoli, salt, pepper, and olives. Combine batches. Serve immediately.
