This is a favorite first course for holiday dinner parties. We often substitute Gorgonzola for goat cheese and top the oranges with sliced fresh strawberries.
Peel oranges, and cut into 1/4-inch-thick slices. Arrange watercress on a serving platter; top with orange slices. Whisk together canola oil and next 5 ingredients; drizzle over salad. Sprinkle with goat cheese and pecans.
