I discovered this one from Shady Maple Farms, it is very simple and delicious…
Wash the broccoli and cut into florets.
Cook until tender-crisp in boiling, salted water.
Meanwhile, whisk together the vinegar, maple syrup, and mustard.
Gradually whisk in the walnut oil.
Place the cooked broccoli in a shallow serving dish.
Pour the vinaigrette over the broccoli and sprinkle with walnuts. Serve immediately.
This attractive dish works equally well with Brussels sprouts or cauliflower.
