Arrange broccoli in a steamer basket over boiling water. Cover and steam 4 minutes or until crisp-tender. Plunge broccoli into ice water to stop the cooking process; drain.
Heat butter in a large nonstick skillet over medium heat 2 to 3 minutes or until melted. Add broccoli, pecans, salt, and pepper. Cook, stirring gently, 2 to 3 minutes or until thoroughly heated.
