Heat a large pot of lightly salted water to boiling. Add broccoli to water and cook 3 minutes. Scoop broccoli from water and transfer to a 12-inch skillet, along with oil.
Return water to boiling and cook pasta as package directs. Drain and transfer to a serving bowl. Toss with butter, 2 tablespoons of the lemon juice and the garlic salt. Keep warm.
Meanwhile, heat broccoli and oil over medium-high heat until sizzling. Add garlic and shrimp. Cook for 3 to 4 minutes, or until shrimp is cooked. Add remaining 2 tablespoons lemon juice, salt and pepper. Stir in bread crumbs and serve over rotini.
