Step 1

Bring a large saucepan of salted water to a boil. Add the broccoli florets and stems and cook until bright green and just tender, about 5 minutes. Drain and rinse the broccoli under cold water until cooled; pat dry.

Step 2

In a large bowl, whisk the olive oil with the vinegar, lemon juice, lemon zest and shallot and season with salt and pepper. Add the broccoli, toss to coat and serve.
