Cut the florets from the broccoli.
With a vegetable peeler, peel the stalks, and slice 1/2 inch thick.
Bring a large pot of water to a boil. Immerse the broccoli florets and stalks in the boiling water for 1 to 2 minutes, until bright green. Drain and cool.
In a bowl, mix the broccoli, tomatoes, and blue cheese dressing. Season with salt and white pepper.
