1 tablespoon white-wine vinegar
1/4 teaspoon Dijon mustard
2 1/2 tablespoons extra-virgin olive oil
1 large navel orange
1 small firm-ripe avocado (preferably California)
2 Belgian endives
3 slices bacon, cooked until crisp and crumbled fine
In a small bowl whisk together vinegar, mustard, and salt and pepper to taste and whisk in oil in a stream until emulsified.
With a sharp knife cut peel and pith from orange and cut sections free from membranes. Cut sections into 1/2-inch pieces and transfer to a bowl. Peel and pit avocado. Cut avocado into 1/2-inch pieces and add to orange. Trim endives and slice thin crosswise. Add endives and dressing and toss salad lightly. Sprinkle salad with bacon.
